[WIP] VSE: Transform overwrite mode

WIP status: logic is implemented, and overwrite mode is currently forced.

Add mode to overwrite strips on overlap instead of resolving overlap.
When overlap is created, 3 things can happen:
- On partial overlap, handles of overlapped strip are moved
- On complete overlap with smaller strip, overlapped strip is split
- On complete overlap with larger strip, overlapped strip is removed

There are some edge cases where this mode may not work very well, this
is mainly case for partial overlap with effects. This situation can be
resolved in more than one way and I don't think it can be predicted.

GPencil: Cleanup transformations

Merge branch 'master' into soc-2021-porting-modifiers-to-nodes-remesh-blocks

Merge branch 'master' into soc-2021-knife-tools

Knife: Fixed undo not working with cut through

The number of new cuts recorded each undo frame was set based on linehits.
This broke when cut through was enabled.
Solution was to increment the new cuts count every time #knife_add_single_cut is ran.

Merge branch 'master' into soc-2021-porting-modifiers-to-nodes-remesh-voxel

removed makesrna from includes in CMakeLists.txt

Use a modal keymap entry to toggle node unlinking with ALT.

GPencil: Add option to reset center of the asset

adaptive_cloth: AdaptiveMesh: set and retrieve `Node`s extra data

From the `Cloth::verts`, set the extra data in the `Mesh::nodes`.

Delete the `Cloth::verts` to not have duplicate data.

Allocate data for `Cloth::verts`, and set from the `Mesh::nodes`.

adaptive_cloth: Mesh: get elements mutably

Useful to get the elements mutably.

This does make `Mesh` less "safe" since anyone can add or delete
elements without creating/deleting the necessary referencing between
the elements but this shouldn't be too much of a problem because it
would lead to an instant forced crash when the `Mesh` is used for
anything.

GPencil: More work to import asset (WIP)

adaptive_cloth: BKE_cloth_remesh: convert to and from AdaptiveMesh

adaptive_cloth: Sizing: get edge size squared

adaptive_cloth: VertData: initial implementation

Used to store extra `Vert` data in the `Mesh`.

adaptive_cloth: NodeData: initial implementation

Used to store extra `Node` data in the `Mesh`.

adaptive_cloth: BKE_cloth_remesh() add to namespace blender::bke

Add operator properties to transform for toggling node link intersect.

bli: float2x2: multiply matrix with float

bli: float2x2: add 2 matrices
