New base build option for LLVM (Apple) bitcode support

When building with clang on macOS, you can now build your static and shared binaries with embedded bitcode by enabling the b_bitcode base option by passing -Db_bitcode=true to Meson.

This is better than passing the options manually in the environment since Meson will automatically disable conflicting options such as b_asneeded, and will disable bitcode support on targets that don't support it such as shared_module().

Since this requires support in the linker, it is currently only enabled when using Apple ld. In the future it can be extended to clang on other platforms too.
