Ryan Macnak e31c3713bf Reland "[build, vm] Access TLS with less code."
- Avoid TLS initialization checks by using inline initialization.
 - Avoid global offset table indirection by reducing -fPIC to -fPIE.

out/ReleaseXARM64/exe.stripped/dart_precompiled_runtime
11137992 -> 11274776 (-1.21%)

We still need -fPIC in some places because we build a few shared libraries for FFI, so copy some of Fuchsia's GN setup to use -fPIE or -fPIC as appropriate.

Account for older gcc that does not default to -fpie.

This directory was taken from a snapshot of flutter/engine/src/build/.

The snapshot was taken with a recursive copy cp -R of the directory from the flutter repository.

The contents has now diverged significantly from Flutter, and is maintained independently by the Dart team. It is used to support the GN build system.
