install_deps: update some libs, and various improvements/fixes.

This commits:
- Updates some libraries to latest officially supported versions:
** Numpy: 1.17.5
** OCIO: 1.1.1
** OIIO: 2.1.15
** OSL: 1.10.10
** OIDN: 1.2.1

- Re-enables some distro packages (like OSL, OIIO, OCIO...).

- Add missing 'CMake cleanup commands' for generated CMake update
command, for Embree, OIDN and OpenXR.

- Generalizes using min/max versions of accepted libraries, if no
package can be found in specified range then it is built from sources.

The later point should help keeping things a bit in better conditions,
although current maximal accepted versions are somewhat arbitrary guess
currently.

Cleanup some building errors with ClangTidy.

Fix T75588: Missing loop cuts preview for edges without quads

The preview of points was only done when the edge is wire.

Now the preview of points is done when the edge is not connected to any
quad.

Also to avoid edge slide in this case, all new vertices created in this
specific case are not selected.

Merge branch 'blender-v2.90-release' into master

fixed bug in ldlt

GPencil: Refactor: Make return more explicit

params should be animatable

Fix vertex offsets for MEdges and MLoops.

Merge branch 'blender-v2.90-release'

Fix T79563: Compositor's Stabilize 2D in invert mode does not work correctly

Is not only the values of translation/scale/rotation which are to be inverted,
but also the order of operations.

Fix T79616: Sort by column in filebrowser is broken

After changes in rBc606044157a3, mouse press events would be blocked by
the selection operator. This only worked by chance before.

WIP: handle clog in separate TextViewContext

- add separate set of operators to deal with clog - they are currently logical mirror of reports but will be expanded
- remove pointless flag RPT_FLAG_NONE
- remove active_reports from SpaceInfo as logs are no longer converted to reports

Merge remote-tracking branch 'origin/blender-v2.90-release'

Revert "Fix T77409: Crash showing vertex/face duplicators in edit-mode"

This reverts commit 9adedb26055f03263fefba380980ee2abcb5327e. It changes
how duplis work, and by that altered how Alembic and USD files are
written. This was signalled by a failing Alembic unit test.

UI: Separate log filtering and formatting

GPencil: Split Primitive operators and add number of points to Topbar

Now the operators are split to define different default values. This is also required for the future Bezier primitive tools.

This allows to show in the Topbar the number of subdivisions. Before this value was totally hidden and it was number of Edges. The wheelmouse can be used to override the value while running, but does not change the default value.

{F8766270}

All operators share same code.

Also, fixed some bad practices done with Toolbar in python.
