Replace `NULL` with `nullptr` in C++ code.

Clang-Tidy: error out when executable not found

Stop with an error when the Clang-Tidy executable cannot be found.

Without this check, CMake will happily report "Found Clang-Tidy" but with
the fallback version (0, 0, 0), when `CLANG_TIDY_EXECUTABLE` points to a
non-existing executable.

Fix T81997: Subsurf Optimal Display sticks after object conversion

When using Optimal Display, some edges are not flagged `ME_EDGEDRAW` |
`ME_EDGERENDER`.
When the modifier is applied through the UI in the modifier stack this is
not an issue because the `modifyMesh` callback is run with
`MOD_APPLY_TO_BASE_MESH` (this will effectively turn of Optimal
Display).
When converting to mesh though, this will just get an evaluated mesh
(where the edge flags are still the same as with the subdivision
modifier).
Now ensure every edge is flagged to draw after conversion.

Fix T82251: Outliner Material Drag&Drop missing tree update

Caused by rBb077de086e14.

Not entirely sure why this was rebuilding the tree prior to above
commit, but sending an ND_OB_SHADING notifier is appropriate (and also
what the Outliners listener listens to).

Fix T82220 Missing viewport update after manual "HDRI Preview Size" input

This is caused by the TAA being reset after the init phase, leading to
1 sample being kept as valid when it is clearly not.

To fix this, we run the lookdev validation before TAA init.
