Fix T80224: Crash after duplicating and hiding vertices while using X Axis Mirror

The mirror map can reference a hidden vertex that is currently ignored
in the transformation.

Thus the mirror element array is not filled.

Fix ugly alignment of "Mono" option in the Sequencer

Steps to reproduce were:
* Open Sequencer, add a sound strip
* In the sidebar, open the Adjust > Sound sub-panel
* Note the placement of the "Mono" item

The layout code would disable decorators if a property came from a
non-animatable data-block type. Doing so would mess up the alignment
where properties from different data-block types were be mixed.
This is not the case any more.

Note that when actually adding the decorator, a blank icon is inserted
to keep the alignment intact when the data-block type isn't animatable.
So the decorator is still not shown, but the alignment looks fine.

This may affect more cases. If so, and if that's an issue, the
decorators should be explicitly disabled.

Fix (unreported) GPencil cannot deselect points with box/lasso select

Selecting in empty space wasnt considered as 'changed'.

Fix T80328 Commit introduced build warnings in Windows

Gizmo: Navigate: Make use of UI_draw_roundbox_4fv

This improves circles AntiAliasing, and line antialiasing.

This keeps the old drawing method (3d spheres) for the selection pipeline.

This was suggested by @harley on devtalk.

UI: Widget: Add conservative raster to avoid cut widget borders

This avoids incorrect AA when the widget is not perfectly alligned with the
pixel grid.

Transform: Keymap: Enable Auto Constraint with Middle Mouse + Shift

Transform: remove MOD_CONSTRAINT_PLANE

It conflicts with MOD_PRECISION and was not really working properly.

Fix constrain plane masking shift event

This prevented transformation with a precision modifier.

Fix T80258: UILayout.prop_search() issues with datablock names

If the search menu was used for a string property, and a data-block was
selected from the search, the value set would be an invalid name. The
property would get the modified UI string, not the proper data name set.

This problem was already once solved in rB249ccab111ac, but resurfaced
in rB937d89afba36.

Now only use the modified UI string if requires_exact_data_name is not
true.

Note: the comments in rB249ccab111ac [reg. library hints and string
properties, also that pointer properties are preferred over string
properties when dealing with IDs] still apply.

Fix T64267: 'Add Snap Point' does not work with Ctrl pressed

Transform: Move some hardcoded keyitems to keymap_data in python

Keymaps must be customized by the user.

But this is not the case for hardcoded keymaps.

Also the repetition of hardcoded and user-defined keyitems may induce
the user to think they have made a mistake or it is a bug.

Cycles: Fixed Cycles standalone build.

The node refactor in 429afe0c626a was missing in the standalone code.

Fix double include of `gmp.cmake`

This fixes `make deps` complaining about the `extern_gmp` project being
defined twice.

Sequencer: Fix crash caused by stereo rendering fix

Caused by rB2e908156d0c7

This was caused by the sequencer timeline area not using a GPUViewport
but still using `sequencer_draw_preview`.

Cleanup: GPUContext: Remove unused functions

OCIO: Make GLSL implementation use GPUUniformBuf to avoid debug errors

Now that we use internal state info, we require drawing that uses the
GPU api to use it throughout the whole pipeline. This is in order to
track the GL state and do our own error checking.

GPU: Move UBO binding validation to GL backend

This also make the validation quicker by tracking the currently
bound slots.

EEVEE: Volumetric: Fix Mesa Compiler error

The compiler does not seems to understand the `const` in the
function declaration and complains about non constant indexing
of unsized array.
