py api: BMesh.from_object() was using the derivedFinal, which isn't always available - or may not have UV data if in the wireframe view.

update the function to calculate the derived mesh with bmesh data-mask each time.

resolves bug [#33205] Bmesh "from_object" gives "no usable mesh data".

also found 'mesh_build_data' could run with non mesh objects and fail silently - add an assert.
