GPencil: Fix unreported missing Sculpt/Vertex/Weight paint brushes

This error was introduced wit the change in commit https://developer.blender.org/rB6a850f3cc840

As the brushes were not created, all modes except Edit were broken.

Now, the brushes and palette are not created when load the file in versioning code, but when the mode is enabled.

Also, if the brush already exist, the parameters are not reset as it was done in the versioning code in order to keep user settings.

The same logic is used for the default palette.

Fix T76563: Transforming an auto-aligned point won't set it aligned

When local origins are used or a single control point is selected,
change the handle types from auto to aligned.

Cleanup: Put GPU_state_init inside gpu_state.c

Also put glDisable(GL_DITHER) in it since we don't even use it (but is
enabled by default).

Also leave GL_MULTISAMPLE on by default since it has no impact on non-MSAA
framebuffers.

Libmv: Fix crash solving when having negative frames

Don't use linear array with frame as an index since it has the
following disadvantages:

- Requires every application to take care of frame remapping, which
could be way more annoying than it sounds.

- Inefficient from memory point of view when solving part of a footage
which is closer to the end of frame range.

Using map technically is slower from performance point of view, but
could not feel any difference as the actual computation is way more
complex than access of camera on individual frames.
