Move build flags to generated file, stop using cflags

Design doc: go/perfetto-buildflags
Stop passing -DPERFETTO_XXX to cc invocations.
In GN builds, use a perfetto_build_flags.h file generated
at build-time via genrule. For Android, Blaze/Bazel and
amalgamated builds, generate the header when running
tools/gen_xxx, check it into build_configs/xxx/,
point include_dirs that directory in each build system.
This CL also cleans up some GN files that were using
build_with_embedder for the wrong purposes (to check
whether we should use //gn/standalone or the
embedder-provided GN files). The amalgamated build needs
embedder=true but uses standalone GN.

Test: manually tested the following:
  - tools/gen_amalgamated: builds
  - manual chrome roll (linux): builds
  - manual v8 roll (mac): builds
