Size verifier fix 2 (#8740)

Browse Source 
* Fixes to make SizeVerifier work.

In particular change all the places in the Flatbuffers library
and generated code that were using `Verifier` to instead use
`VerifierTemplate<TrackBufferSize>` and wrap them all inside
`template <bool TrackBufferSize = false>`.

Also add unit tests for SizeVerifier.

* Format using `sh scripts/clang-format-git.sh`

* Use `B` rather than `TrackBufferSize` for the name of the template parameter.

* Update generated files.
