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).
