[roll] Roll fuchsia [flatbuffers] Update to a56f9ec50e908362e20254fcef28e62a2f148d91

BUILD.gn and flatbuffer.gni are adapted and copied from Chromium
respectively. The latter retains Chromium's license header because it is
used unmodified.

https://source.chromium.org/chromium/chromium/src/+/main:third_party/flatbuffers/

Remove the non-zero default value of Quat as flatc now produces:
  src/ui/scenic/lib/gfx/snapshot/snapshot.fbs:15: 14: error: default values are not supported for struct fields, table fields, or in structs.

This default value appears not to be load bearing:
  $ git grep snapshot::Quat
  src/ui/scenic/lib/gfx/snapshot/serializer.h:  snapshot::Quat rotation = {0.0, 0.0, 0.0, 1.0};

Replace the deprecated `flatbuffers::Vector::Length` with
`flatbuffers::Vector::size`.

The UBSAN suppression is removed.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party
