Use expanding buttons layout for modifier box headers

Had to fix a crash in the alignment code for too small areas.
Also changed panel type flag defines to use an enum.

Remove redundant leading 'Bevel' header in Bevel Geometry sub-panel

Bevel modifier: Group Profile and Custom Profile together

Fix layout issue in Bevel modifier Limit Method

Cleanup: Consistent code formatting

Merge branch 'master' into modifier-panels-ui

Draw list panels with box widget colors and code

This solves the transparency and theming issues by reusing the theming
from the box widget. This requires a new drawing function in order to
use box drawing with an opaque inner color, alpha blended with the
region's background color.

Fix T75730: Properly remove unused override properties/operations.

While code is supposed to handle gracefully invalid override operations,
it is much cleaner to avoid those completely.

GPU: Fix Negative Shift

glAttributes also include `gl_` names. These don't have a location and
should be ignored during shader interface creation. Those internal names
received a location of -1 and therefore the bitmasking was undefined.

Users wouldn't notice this, but ASAN warned developers of this situation.
ASAN could quit making ASAN un-usable as most shaders have this issue.

UI: Remove old hacks for dynamic scrollbar hiding

Although we still dynamically hide scrollbars, they don't change the
region size anymore. They are simply drawn on top of the region content.
Because of this, some hacks introduced by fa28e50ac2a7 are no longer
necessary.
Without these hacks, the scrollbar visibility is evaluated much more
often (cheap operation) which should be more reliable and possibly solve
some glitches.

Also replaces integers passed as booleans.

Fixes T75782.

Fix T73977, T73825: ignore Python user site-packages directory by default

This goes along with the existing changes to ignore PYTHONPATH by default.

UI: Draw real node sockets for node input buttons

For buttons representing node inputs (e.g. in the material properties)
rather than drawing some generic socket icon, the actual sockets are
drawn now. That includes color, shape and the selection outline.

This should make it easier to understand what these buttons relate to.

Screenshots: {F8469252}, {F8469248} (The left alignment will be done in
a follow-up commit.)

Fix T74964 Stereo 3D anaglyph and interlace not working

Caused by framebuffer initialized in the wrong context.

UI: Move node socket icons to the left of node input buttons

Node input buttons (e.g. in the material properties) used to draw their
icons on the right of the buttons. However since they represent inputs,
it makes more sense conceptually to have them on the left.
Further, we might want to add the usual decorator buttons (to control
keyframes or display other states) to the material properties as well.
Having two circle icons next to each other would be confusing.
