[PATCH v2 3/4] Makefile: reintroduce REFTABLE_OBJS

In the next commit we are about to precompile "git-compat-util.h" with "make" to reduce build times. But using the precompiled header should not change what actually gets compiled, therefore a source file can only be compiled using the precompiled header if the first included header file is "git-compat-util.h".

The reftable source files are kind of special, because the reftable implementation is supposed to be easily includable in other projects. Therefore, the reftable source files don't include "git-compat-util.h", with the sole exception of the purposefully project-specific "reftable/system.c". Consequently, they shouldn't be compiled with our precompiled header.

List object files under "reftable" in the REFTABLE_OBJS Makefile variable, so in the next commit we'll be able to easily filter them out and keep building them the old way, without the precompiled header.

Note that object files under "reftable/" used to be listed in REFTABLE_OBJS so we could build a static library from them. This static library was removed in f3b4c89d59 (make: delete REFTABLE_LIB, add reftable to LIB_OBJS, 2025-10-02), along with filling REFTALBE_OBJS with object files. This change essentially reverts the removal of REFTABLE_OBJS, but not the building of that static library.
