This PR enables building the mmtk-julia binding with different configurations other than non-moving Immix. While it was already possible to do so when building from source, this should enable using the binaries generated via the latest version from BinaryBuilder (JuliaPackaging/Yggdrasil#10357).
I have also decoupled MMTk from the code, such that it should be an option for a third-party heap. This should be set using WITH_THIRD_PARTY_GC=mmtk (in Make.user or as an environment variable).

The different configurations of MMTk can be achieved by setting the variables below (set in Make.user, for example):

Variable
MMTK_PLAN Immix StickyImmix
MMTK_MOVING 0 1
MMTK_BUILD release debug

Note that the actual code to support building with moving and sticky immix will be added in future PRs.
I've also added some preliminary documentation in doc/gc.md about building Julia with MMTk, including a link to the binding and an small FAQ on what to do if you break the build of Julia+MMTk.
