Revert "[TextAPI] Add missing link to libObject" and "[TextAPI] Add DylibReader (llvm#75006)"

This reverts commit aa217eb.
This reverts commit 634fedd.

This breaks buildbots by introducing cycle dependency between libObject
and TextAPI and breaks gcc compiles on buildbots.

(cherry picked from commit 1fef0fa)
