Object Mode: add back non '_ex' versions of mode-switching functions

While these aren't currently used, its strange to have
extended versions of a function without the non-extended versions
it also avoids callers needing to add them back if they need -
or duplicating the same boiler plate when calling the '_ex' versions.

Reverts 11da3b132aff1, 11da3b132aff1, adds depsgraph argument
so the caller is responsible for the evaluation state.
