Headers should only include other headers when absolutely necessary,
to avoid unnecessary dependencies and increasing compile times.
To make this change simpler, three DerivedMesh functions with a single
use were removed.
Knowing when layers are retrieved for write access will be essential
when adding proper copy-on-write support. This commit makes that
clearer by adding `const` where the retrieved data is not modified.
Ref T95842
Works for both Cycles and multires bake. Triangles are baked to multiple
UDIM images if they span across them, though such UV layouts are generally
discouraged as there is no filtering across UDIM tiles.
The bake margin currently only works within UDIM tiles. For the extend method
this is logical, for the adjacent faces method it may be useful to support
copying pixels from other UDIM tiles, though this seems somewhat complicated.

Use a shorter/simpler license convention, stops the header taking so
much space.

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they

The new adjacent faces method border lookup fails in some directions around
45 degrees
* Use 8 Dijkstra directions (also diagonally) to determine which polygon is the
closest to each pixel. Using only Manhattan distance lead to large parts of
the texture which were matched with the wrong polygon.
* Use neighbroing polygons for edge search. The Adjacent Faces algorithm needs
to determine the closest edge, in UV space, each pixel. To speed this up
first as map is built which finds the closest polygon for each pixel along
horizontal, vertical and diagonal steps. Because this can sometimes be one
edge off we first look in the polygon from the map, if that fails also
check the edges of its neighbouring UV polygons.

This significantly reduces discontinuities on UV seams, by giving a better
match of the texture filtered colors on both sides of the seam. It works by
using pixels from adjacent faces across the UV seam.
This new option is called "Adjacent Faces" and is the default. The old option
is called "Extend", and extends border pixels outwards.
