Fix T71311 Bridge Edge Loops crash when bridging cube edges

This commit will prevent the crash. It does produce a result that may not
be desirable (only briding one face of the cube), but at least it's better
than crashing.

Fix T73279: Particle Rotation checkbox enabled when a bake exists

The contents of the Rotation panel was already disabled when a bake
exists, but the checkbox in the header wasn't. Since rotations are part
of the baked data, it doesn't make sense to enable/disable rotations
after baking.

Fix T72459: Mask Modifier breaks Vertex Parenting

The `give_parvert()` function was only considering the mesh's original
vertex indices when the parent vertex index was valid for the evaluated
mesh. However, when using the Mask modifier the evaluated mesh can have
less vertices but still have the parent vertex.

Since the `if (nr < numVertex)` condition wasn't used to prevent any
out-of-bounds access, and seems just an incorrect optimisation, it could
be removed.

Fix T72216 Copied Particles not refreshing in the viewport

The depsgraph was not tagged for relations update after the copy, which
means it was incomplete and thus didn't update the copied particle sim.

Fix T70891: Motion Path - Changing endframe clamps startframe to 1

There were two strange things going on:

- Start frame was clamped to 1, even when frame 0 is always a valid number.
This also ignored the 'Allow Negative Frames' user preference.
- Start frame was only clamped when setting the end frame, so first setting
the end frame and then the start frame would result in a different result
than doing it in the opposite order.

This commit fixes both issues by:

- Clamping the lower bound of the start frame only if negative frames are
not allowed, and
- apply that clamp both when setting the start and the end frame.

Fix T72213: F-Curve animation does not update FreeStyle properties

FreeStyle line styles were not part of the dependency graph, and
blacklisted from the Copy-on-Write system. As a result, animated
FreeStyle properties would not be updated by the animation system,
resulting in T72213. There was an explicit call to run the animation
system on the original datablocks, but that was (for good reasons)
removed in D5394.

This commit adds the FreeStyleLineStyle datablocks to the dependency
graph and allows them to be handled by the CoW system. As a result

- the UI now updates properly when properties are animated, and
- animated property values are actually used when rendering.

This commit includes @Sergey's patch P1222, which unifies two bits of
code that did the same thing: check whether datablock type is covered by
copy-on-write.

Fix T71825: Custom Animation Player path overrides chosen player

Thanks @mano-wii for providing the patch!

The original code assumed that when `animation_player_preset` was not
`CUSTOM`, the `animation_player` path would be empty. This is a bad
assumption, as it can be quite useful to be able to toggle between a custom
and a built-in player. As such, `animation_player` should not be reset to
an empty string when a non-custom player is chosen.
