UI: Use property split in vertex paint symmetry panels

Set property split in the higher level panel functions so that it carries
over to buttons added after. Also discard the redundant "Symmetry"
to make sure there is enough space for the checkbox label.

UI: Fix Symmetry options in weight paint panels

The now redundant "X" checkbox is removed since it's also present in the
Symmetry panel above. The Topology Mirror is moved into the Symmetry
panel also.

This was needed because `Mesh.use_x_mirror` has recently been turned into
different functionality, and its old functionality now lives under
`Mesh.use_mirror_vertex_group_x`. Something went wrong in the UI in This
transition.

Split BKE_sequencer.h intern/extern definitions

Intern definitions are moved to sequencer/intern/sequencer.h

BKE_sequencer.h was also cleaned up a bit to make sure that functions
and structs are in correct category.

Fix Recursion when rendering scene strip

Recursion happens in case when scene strip point to it's own scene
indirectly by using SEQ_SCENE_STRIPS option.

Fix T81426: Infinite loop building VSE relations

It is possible to create scene strips pointing to each other. This is
sanitized when rendering, but in dependency graph such setup will cause
infinite loop.

This patch fixes loop in dependency graph, but same problem exists in
audaspace

Fix T81250: Crash after undoing with prefetching

Main DB and it's structs can point to different address after undoing.

In this case problem was that bmain was not updated. Same fix was

Fix T81904: Cloth brush simulation failing with local area and mirror

When using local area, all nodes need to build their constraints first
before activating them for simulation. THis ensures that nodes get their
structural constraints from the initial location of each symmetry pass.

Sculpt: Implement plane deformation falloff for Grab

The plane deformation falloff was introduced in the first version of the
cloth brush, but due to the lack of all the new features and fixes in the
solver it was causing a lot of artifacts for deformation brushes. In
order to avoid that, the cloth brush was always using radial falloff for
the grab brush.

Now the plane falloff is properly implemented using the deformation
constraints.

Sculpt: Option to limit the action of line gestures to the segment

This adds a tool property for sculpt line gesture tools (line and
project) to limits its effect to the segment of the gesture instead of
using the infinite line to bisect the mesh in two parts.

To achieve that, the line gesture now has two extra side planes that can
be enabled/disabled for getting the nodes from the PBVH and to test the
vertices.

Sculpt: Face Set Edit delete Geometry operation

This adds an operation mode to the Face Set Edit tool which deletes the
geometry of a Face Set by clicking on it.
The operator also checks for the mesh having a single Face Set to avoid
deleting the entire object by accident.
This is also disabled for Multires to avoid modifying the limit surface
without control (it is not an important limitation as base meshes for
multires are usually final, but maybe it can be supported in the future).

Fix T82019 Crash loading 2.78 splash demo.

The versioning code to default to old booleans for old files was
faulty because really old files had a 'solver' field (later removed,
but then added back for new booleans).
