the public API (#7011).

* 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.
* clang-format
* Make the flatbuffers Rust crate only have an optional dependency on the `serde` packages.
* fix warning
* fix rust test build
* Oh yeah this needs to be initialized
* fix toml syntax
* code review feedback
* rebuild test data
* benchmark many vtables
* Rust: Store written_table rev-positions sorted.
The previous implementation was slow if there were too many tables.
Asymototically when inserting the n^th vtable: The old implementation
took O(n) lookup steps and O(1) insertion. The new implementation is
O(log n) lookup and O(n) insertion. This might be improved further by
using a balanced btree.
Benchmarking, create_many_tables is 7.5x faster (on my laptop):
// Simple vector cache
test create_many_tables ... bench: 728,875 ns/iter (+/- 12,279) = 44 MB/s
// Sorted vector cache
test create_many_tables ... bench: 97,843 ns/iter (+/- 4,430) = 334 MB/s

how `Vec` does it.

* Fix Miri flag passing and bump Rust version.
* Fix Miri problems from Arrays PR.
SafeSliceAccess was removed for Arrays. It's kind of unsound.
It has two properties:
1. EndianSafe
2. Alignment 1
We only need 1. in create_vector_direct to memcpy data.
We both 1. and 2. for accessing things with slices as buffers are built on &[u8]
which is unaligned. Conditional compilation implements
SafeSliceAccess for >1byte scalars (like f32) on LittleEndian machines
which is wrong since they don't satisfy 2.
This UB is still accessible for Vectors (though not exercised our
tests) as it implements SafeSliceAccess. I'll fix this later by
splitting SafeSliceAccess into its 2 properties.

* Rework enums in rust.
They're now a unit struct, rather than an enum. This is a
backwards incompatible change but the previous version had UB
and was also backwards incompatible so...
* Update and test sample rust flatbuffers
* Use bitflags crate to properly support rust enums.
Previously, the bitflags attribute was just ignored. This is a breaking change
as the bitflgs API is not like a normal rust enum (duh).
* variant_name() -> Option<_>
* repr transparent
* Reexport bitflags from flatbuffers
* Make bitflags constants CamelCase, matching normal enums
* Deprecate c-style associated enum constants
