Merge code will generate temp normal editing data for affected loops,
but since it will later (by setting some edges/faces to smooth) alter
and extend affected clnor spaces, it will also need temp normal editing
data for some other loops around those vertices...
Using those clnor editing data in that code is a bit of an abuse, but on
the other hand that struct stores exactly what we need.
So simply added an option to generate that editing data for all clnors
of affected vertices.
This patch does not bring functional changes, but it is a good change if we want to use these utilities in areas other than those using BMesh (eg painting editors).
This is also a step to replace `ED_view3d_select_id_validate`. That function erroneously checks `V3D_INVALID_BACKBUF` which causes it to update unnecessarily.

Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.
Also added several missing strings (including the one reported in D5056
by Jean First (@robbott), thanks).
The fix itself is by Germano Cavalcante (mano-wii).
But since I was investigating this with him, I'm including here an
assert in EDBM_select_id_bm_elem_get to help catching this sooner
in the future
The previous fix 8a6414ed46, resolved selection picking but didn't
work for box/circle/lasso select.
- Add ED_select_buffer_utils.h for general select-buffer operations
unrelated to edit-mesh.
- Circle select still needs to cache select-id's for each update.
This patch does not bring any functional change, but it does expose
some utilities that can be very useful to correct occlusion and
performance problems of Circle Select and similar.
Creating a selection context still makes it easier to track issues.
- Add missing tooltips to Quick Effects and Subdivide Edge Ring
- Add proper tooltip to the Bevel operator
- Clearer tooltips for the extrude operators
Plus a few other tweaks
Suggested by users on Devtalk.
- Move connected & projected into individual toggles.
- Top-level proportional editing button now only toggles.
- Use popover for proportional edit-mode falloff and options.
Note that it's no longer possible to toggle connected via key bindings,
although this could be supported again if it's needed.
