Fix RegionStore assertion failure after #127602 (#129224)

Basically, we may leave the loop because if exhaust the fields, array
elements or other subobjects to initialize.
In that case, the Bindings may be in an exhausted state, thus no further
addBinding calls are allowed.

Let's harden the code by sprinkling some early exists in the recursive
dispatcher functions.
And to actually fix the issue, I added a check guarding the single
unguarded addBinding right after a loop I mentioned.

Fixes #129211
