VSE: cache performance optimization

Map frame for cached raw images to strip input media frame range. This
means that static images or extended frame range of movies will only
generate one cache entry.

timeline_frame is stored in cache key as a reference - on what frame
was this entry created, so we don't have to reverse lookup frame range.

Since each media frame corresponds to one cache frame with same frame
index key, there is no need to invalidate raw cache when changing time
remapping properties like use_reverse_frames or strobe

No changes are needed for disk cache, since invalidating raw entry
assumes all data will be invalidated.

Fluid: Potential fix for T74559: Adaptive Domain creates lines in smoke

This commit corrects the maximum resolution field in Fluid objects. The field should be set to the maximum possible resolution, i.e. it should not adjust with adaptive domains and stay constant all the time.

The reason for this is that this resolution value will be used to scale gravity. And this gravity should be constant for adaptive domains too.

It remains to be shown if this issue was the only reason for line-artifacts as seen in T74559.

Cleanup: add commits to .git-blame-ignore-revs.

XR: Add "absolute tracking" session setting

Enables users to define the tracking origin in a way that is not
linked to the headset position. Instead, the tracking values given by
the XR runtime are left unadjusted and a user can manually calibrate
an "origin" landmark object to adjust to their real world space.

Can be useful for applications that use external tracking systems
and those that primarily only need to use controllers (e.g. for
motion capture).

Rename extern rendering and proxy functions

Replace BKE_sequencer wirh SEQ_render or SEQ_proxy prefixes.
In cases where function is very generic, only SEQ prefix is used.

Cleanup: split sequencer.c file

Move functions closely related to rendering images and proxies into
render.c and proxy.c files. render.h and proxy.h are created for
functions used internally.

There should be no functional changes.
