GN: add is_official_build
... and use it to control debug symbols and SK_ALLOW_STATIC_GLOBAL_INITIALIZERS.
This will most directly have the effect of disabling GLProgramsTest and a bunch
of similar failing Vk tests on Android.
Hopefully this makes the N7 trybot go green, keeping the N5 trybot green. Just running the N10 for fun.
(is_official_build is how Chrome terms this sort of ReleaseForReal build.)
