Merge branch 'master' into mesh-transfer-data

"Better" solution to avoid infinite recursion in dependency cycles of DataTransfer modifier cases.

Note, issue here is that in modifier case, we can't be no more sure to actually get required
datalayers from source dm...

Forbid dependency cycle of DataTransfer modifiers, this is just not possible.

(Here I get a segfault inside asan lib iteself, when doing that...)

Cleanup.

Change default mapping to 'nearest', better than 'topology',
which will error if source and dest are not topo-compatible.

Missed those when reordered loop vs poly code.

Better UI for modifier, based on feedback from first review.

More UI name tweaking.

Some UI tweaks (renames only for now), from review.

Attempt to handle better normals stuff.

Note we may ultimately decide to just always compute loop and poly nors...
This would be a shame in some cases (we'll have several modifiers using those data
soon), but caching it in a reliable way is not that easy.

Add early error reporting about mismatched number of items in case of 'Topology' mapping.

Use reports system here...

Replace grid-sampling by random tess-based one, for face's normal projection sampled mapping method.

Based on review & suggestions from Campbell, many thanks.

This commit adds a new func to BLI_geom, `BLI_tri_v2_sample_random_point()`, which uses
given 2D tri and random generator to generate a random point on that triangle.

Cleanup: use 2d vector functions & minmax from BLI math
