* Bazel support for esbuild-based flatc

Unfortunately, we lose typing information because the new esbuild method
of generating single files does not generate type information.

The method used here is a bit hack-ish because it relies on parsing the
console output of flatc to figure out what to do.

* Try to fix bazel build for when node isn't present on host

* Auto formatting fixes

* Fix missing generated code

920f3827a0 [C++] Add Command-Line Flag to Suppress MIN and MAX Enums (#7705)
Add the --no-minmax-values flag to prevent flatc from generating C++
enums with MIN and MAX enumerated values that otherwise would be set
to the inclusive lower and upper bound respectively of the enum.

This command-line flag is needed to avoid collisions when an enum that
is being ported to FlatBuffers already has a MIN or MAX enumerated
value.

It is also needed to work around a long-standing problem with
magic_enum that causes magic_enum to not see enumerated values that
are not unique.  For example, if FlatBuffers sets MIN = FOO and MAX =
BAR, MIN and FOO share the same underlying value so they are not
unique.  The same is true of MAX and BAR.  This prevents magic_enum
from converting FOO and BAR to and from strings as well as causing
magic_enum to return a count of enumerated values that is two fewer
than it should be.

bb9b9dad5f Fixed the BytesConsumed function, which was pointing slightly ahead. (#7657)
The BytesConsumed function uses the `cursor_` to determine how many
bytes have been consumed by the parser, in case the user of the Parser
object wants to step over the parsed flatbuffer that is embedded in some
larger string. However, the `cursor_` is always one token ahead, so that
it can determine how to consume it. It points at the token that is about
to be consumed, which is ahead of the last byte consumed.

For example, if you had a string containing these two json objects and
parsed them...

    "{\"key\":\"value\"},{\"key\":\"value\"}"

...then the `cursor_` would be pointing at the comma between the two
tables. If you were to hold a pointer to the beginning of the string and
add `BytesConsumed()` to it like so:

    const char* json = // ...
    parser.ParseJson(json);
    json += parser.BytesConsumed();

then the pointer would skip over the comma, which is not the expected
behavior. It should only consume the table itself.

The solution is simple: Just hold onto a previous cursor location and
use that for the `BytesConsumed()` call. The previous cursor location
just needs to be set to the cursor_ location each time the cursor_ is
about to be updated. This will result in `BytesConsumed()` returning
the correct number of bytes without the off-by-one-token error.

a4ff275d9b Added option to not requires an EoF token when parsing JSON (#7620)
Previously when parsing a JSON representation of a Flatbuffer, the
parser required that the input string contain one and only one root
table. This change adds a flag that removes that requirement, so that
if a Flatbuffer table is embedded in some larger string the parser will
simply stop parsing once it reaches the end of the root table, and does
not validate that it has reached the end of the string.

This change also adds a BytesConsumed function, which returns the number
of bytes the parser consumed. This is useful if the table embedded in
some larger string that is being parsed, and that outer parser needs to
know how many bytes the table was so that it can step over it.

e5f331db99 [TS] Add single-file ts codegen & bazel rule for typescript (#7161)
The headline here is adding a flatbuffer_ts_library rule for generating
typescript code in bazel. This entails some non-trivial other changes,
but ideally none are user-visible.

In particular:
* Added a --ts-flat-file flag that generates a single *_generated.ts
  file instead of separate files for each typescript type. This makes
  bazel much happier.
* Import the bazel rules_nodejs stuff needed to support building
  typescript in bazel
* Move flatbuffers.ts to index.ts because I wasn't sure how to make
  bazel comprehend the "main" attribute of the package.json. Happy
  to take another stab at figuring that out if really needed.
* Fix another couple keyword escaping spots in typescript...

615616cb55 Change Rust generated file defaults (#7101)
* Change Rust generated file defaults

After #6731, flatc changed its default behavior
for generating rust code to fix some importing issues.
This was a breaking change which invlidated the patch release,
`flatc 2.0.5` (#7081). This PR reverses the default so we can
release a patch update. However, does break Rust users who work at
HEAD.

1d294a31b8 Implement Serialize on generated rust types (#7022)
* fix for rust build

* Rust: Implement Serialize on generated types

For debugging convenience it is really handy to be able to dump out
types as another format (ie: json). For example, if we are logging a
type to a structured logging system, or even printing it out in a
structured way to the console.

Right now we handle this by shelling out to `flatc` which is not ideal;
by implementing Serialize on the generated types we can use any of the
Serializer-implementing packages for our structured debug output.

b8aaccee82 Disable parsing of nested_flatbuffers as bytes by default
Parsing as bytes produces buffers that are unsafe to access unless passed thru a verifier,
whereas users could reasonably assume that any JSON parsed without errors is safe to access.
Users that still have legacy JSON files with such bytes in it will get a helpful error point them
to the option to turn on to have it work again.

12e341e4f8 Rework how Rust generated files are laid out (#6731)
* Refactored Rust Generated code into a module directory.

Each symbol will be generated into one file and then
imported into a module. This breaks the "out_dir"
pattern where some users would generate code in their
target/ directory. Also, these objects are best used
in their own module. It will be hard for users to share
their own module structure with flatbuffers namespaces.

There may be solutions to these drawbacks but that should
be discussed. I don't want to overengineer here.
