add gb_LinkTarget_reuse_precompiled_header
Similar to gb_LinkTarget_set_precompiled_header, but uses PCH
created by another linktarget. This allows using a PCH even for linktargets
that are small and creating their own dedicated PCHs is not worth it.
The ultimate goal is having some default PCH that will be used if no
explicit PCH is set.
