Dope Sheet: rewrite computation of keyframe hold blocks.

Computation of hold blocks was done by storing ranges (with start and
an end, and likely overlapping) in a tree keyed only by the block start.
This cannot work well, and there even were comments that it is not
reliable in complex cases.

A much better way to deal with it is to split all ranges so they don't
overlap. The most thorough way of doing this is to split at all and every
known keyframe, and in this case the data can actually be stored in the
key column data structures, avoiding the need for a second tree.

In practice, splitting requires a pass to copy this data to newly added
keys, and the necessity to loop over all keyframes in the range being
added. Both are linear and don't add excess algorithmic complexity.

The new implementation also calls BLI_dlrbTree_linkedlist_sync for
its own needs, so the users of the *_to_keylist functions don't have
to do it themselves anymore.

Templates: updated 2D animation template from grease pencil team.

Small change to Annotation panel

Add one line more by default

UI: tweak and fixes for cycles sampling panel, remove unneeded decorators.

UI: put show emitter option in particles panels.

This settings is duplicated from the object duplication panel, but
otherwise it's too hard to find.

Fix remaining copy/paste button header, these are in menus now.

Fix incorrect icon for UV selection sync.

Cleanup: naming

'mp' was a reference to 'manipulator'

Tool System: add gizmo for shear tool

Transform: axis support for shear tool

Fix T57247: Render animation does not respect render single view layer

Event System: don't invoke operator that should only be executed

Problem was that the event was not `NULL` even though the `context` is `WM_OP_EXEC_*`.
I noticed this problem when dropping .blend files into Blender.
Instead of only executing `WM_OT_open_mainfile`, it was invoked (opening a file selector).

The `wm_operator_invoke`, which also executes operators, always invokes operators when `event != NULL`. So setting `event` to `NULL` tells `wm_operator_invoke` not to invoke but to execute the operator.

GP: Set Dopesheet layers in Top-Down order

The layers are Top-Down and the dopesheet must use the same order.

GP: Fix Blur shift when add more samples

The image was moving in +X and +Y when added samples due round precission.

Set Annotation list in Top-Down order

This makes consistent the orders of any grease pencil related list

Fix crash in loose edge check

Cleanup: headers

Mesh: use mesh tessellation for face-map drawing

Also use batch instead of immediate mode.

Cleanup: replace check for derivedFinal w/ mesh_eval
