Hal Canary 32498f0846 GN/ICU cleanup
For targets that depend on ICU, only define if `skia_use_icu` is set.

Move declare_args/skia_use_icu into skia.gni.  Other variables that need
to work like that can move there later.

icu/BUILD.gn defines SK_USING_THIRD_PARTY_ICU if needed.
SkShaper_harfbuzz.cpp SkPDFSubsetFont.cpp respects
SK_USING_THIRD_PARTY_ICU when calling SkLoadICU().

sfntly/BUILD.gn, harfbuzz/BUILD.gn, icu/icu.gni uses $_src variable to
reduce verbosity.   icu/icu.gni adds more headersto sources.

# Some of HarfBuzz's headers are created at build time using the Ragel
# State Machine Compiler.  To reduce complex dependencies, I pre-built
# these files:
#     hb-buffer-deserialize-json.hh
#     hb-buffer-deserialize-text.hh
#     hb-ot-shape-complex-indic-machine.hh
#     hb-ot-shape-complex-myanmar-machine.hh
#     hb-ot-shape-complex-use-machine.hh
# from these sources:
#     ../externals/harfbuzz/src/hb-buffer-deserialize-json.rl
#     ../externals/harfbuzz/src/hb-buffer-deserialize-text.rl
#     ../externals/harfbuzz/src/hb-ot-shape-complex-indic-machine.rl
#     ../externals/harfbuzz/src/hb-ot-shape-complex-myanmar-machine.rl
#     ../externals/harfbuzz/src/hb-ot-shape-complex-use-machine.rl
#
# The files in this directory are created by installing the
# prerequiste packages, checking out a new version of HarfBuzz, doing
# `./autogen.sh && ./configure && make`, then copying the
# autogenerated .h and .hh files to this directory.
