Cleanup: clang-format

Cleanup: unused var

Nodes: Display vector values expanded, except when specified as compact.

Change the default drawing method of vector sockets to use a column layout.
This allows more interactive use of nodes and avoids the one or two clicks
needed to edit vector sockets in the old default component layout.

Developers may still use the component layout by flaging the socket with the
`SOCK_COMPACT` socket flag. For now, we choose to draw the SSS scale vector
of the Principled and SSS nodes in a compact form because they don't require
much interactivity.

GPencil: Refine tooltip for Simplify modifier

GPencil: Hide selection tool in sculpt mode when mask is disabled

The selection tool must be hidden if the sculpt mask is not enabled because these options are not usable in this mode.

Also, the Select tools have been moved to the bottom of the toolbar.

Now, the logic is similar to Meshes.

GPencil: New macros to check Sculpt and Weight Paint modes

Fix T68414: GPencil crash after using L key and Ctrl+Z in Draw Mode

There is a segment fault because the operator was in modal but the Ctrl+Z breaks the custom data. Now, the Ctrl+Z ends the operator.
