Merge branch 'blender-v2.81-release'

Fix issues with make_update.py when run from release branch

The issue was rooting to the fact that the script was iterating into
every directory inside of blender.git/../lib/ and attempted to switch
them to the desired path. This doesn't work in an environment where
both master and release branch are built (or any environment where
non-needed SVN directories are not automatically removed).

This change makes it so script explicitly generates a list of
directories which are required for the build. For example, the script
now stores an exact folder with ABI such as win64_vc14.

Only those explicitly listed directories will be updated.

This allows to:

- Solve compilation failure of 2.81 branch after checkout for
win64_vc15 libraries has been created.

- Fail compilation if actually expected tag is missing (for example,
when trying to build release branch prior to libraries tag).

Now, there was a confusing logic about possible .svn folder in
lib_dirpath (effectively, blender.git/../lib/.svn) which is not
something what is supposed to happen with the setup of buildbot we are
using for quite some time now. This logic has been removed now.

This change includes old-style string format(), mainly because it is
not know that the buidlbot scripts are run using python3 on CentOS
builder.

Make box selection Include Handles option only act on visible handles

The option would previously act on invisible handles. Because of this,
it wouldn't be wise to enable it by default, even though it can be
tremendously useful (esp. with `Only Selected Keyframes Handles`
disabled).
This changes things based on animator feedback, so that we can enable
the option by default.

I can see that for some people even the old behavior of acting on
invisible handles could be useful, so we might consider bringing that
option back. `Include Handles` could then become an enum to chose the
behavior.

Fix T71461: Add IN_PLACE_INSTANCES to `part_prim` and `part_axis` object mode particle shaders

For `Particle Properties -> Viewport Display -> Display As` set to
circle/cross/axis, particle instances are associated with a single
resource handle (and, in particular, a single model matrix), so define
`IN_PLACE_INSTANCES` to get the right index for `ModelMatrix` and
`ModelInverseMatrix` in the shader.
