[roll] Roll fuchsia [fidl][cpp] Move function bodies out of natural & driver headers

This moves almost all function bodies out of generated bindings headers
for natural bindings and both flavours of driver transport bindings.
This means that they're only evaluated and compiled once per build
(modulo toolchain, subbuild, etc). Because these headers are very widely
included this has an impact on the build time for many compilation
units. The remaining function bodies mostly just constexpr functions
associated with bits and enum types.

I compared compile times for one of the slower targets in our C++ build,
src/connectivity/bluetooth/hci/transport/uart/bt_transport_uart.cc and
it reduced the compile time (averaged measured with hyperfine) from an
average of 40.5s to 19.0s, a 53% speedup.

There were some microbenchmark regressions but they were largely in the
setup and teardown parts steps and in benchmarks that don't represent
what's heavily used in production.

Integration

This repository contains Fuchsia's Global Integration manifest files.

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 in one of the communication channels documented at get involved.

Obtaining the source

First install Jiri.

Next run:

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

Third party

Third party projects should have their own subdirectory in ./third_party.
