Windows: Enable `/bigobj` to increase max size for obj files
Equivalent `-Wa,-mbig-obj` for GCC/Clang. This started being needed to compile harfbuzz in `target=debug` with MinGW/GCC, but there doesn't seem to be any drawback to enabling `/bigobj` (aside from losing support for pre-VS 2005 linkers, which we don't support).
