GN: Use lib.unstripped rather than lib.stripped. Add a toolchain.gni
toolchain.gni introduces:
root_shlib_dir, shlib_prefix, and shlib_extension
The original goal of this change was to put shlibs under lib/ for Linux / Android, since that's where GYP puts them. However, the lack of support for loadable_module (or more specifically - per target output directory) in GN makes this infeasible at the moment.
This change also mitigates a subtle bug where on Android the unstripped .so is used mistakenly instead of the lib.stripped/ version. It also fixes shlib's link_output being set to the unstripped .so rather than the stripped .so (on Android).
