Bugfix [#31297] Transform menu often showed operators which didn't make sense
for the contexts they appeared in

The VIEW3D_MT_transform menu was being used everywhere, although not all the
operators there applied to the current mode (e.g. the pivot point, animated
transforms to deltas, and a few others were Object-mode only). Split off the
offending parts into separate menus for the specific modes, and made these
extend the basic menu type.
