matroska: Fix AV1 alignment to TU
...
Matroska stores AV1 in temporal unit, so that all OBU sharing the same
timestamp are put together. This was previously just assumed, which isn't
safe now that we have more alignments.

matroskamux: allow width + height changes for avc3|hev1
...
For avc3 and hev1, the intent was to allow more flexibility for caps changes
(see https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/1047/diffs?commit_id=9bd8d608d5bae27ec5ff09e733f76ca32b17420c )
however width and resolution were previously omitted.
avc3 and hev1 specifically support changing stream-parameters on the fly, whereas avc1/hvc1 disallow in-band SPS.
This commit allows for changes to width and height for these which is in line with matroskamux's behaviour prior to 1.14.0.
Practically speaking, one use case where this is commonly seen is when capturing a WebRTC stream, as the browser will adapt the resolution live.

matroska-mux: Handle pixel-aspect-ratio caps field correctly when checking caps equality
...
Not having this field is equivalent with it being 1/1 so consider
it like that. The generic caps functions are not aware of these
semantics and would consider the caps different, causing a negotiation
failure when caps are changing from caps with to caps without or the
other way around.

matroska-mux: Handle multiview-mode/flags caps fields correctly when checking caps equality
...
Not having these fields is equivalent with them being mono/0 so consider
them like that. The generic caps functions are not aware of these
semantics and would consider the caps different, causing a negotiation
failure when caps are changing from caps with to caps without or the
other way around.

matroska-mux: If a stream has a TITLE tag, use it for the name.
...
If a title tag is pushed to a pad, store it as the Track name.
This means that players will use it as the human readable
description of the track, instead of something generic like 'Video'
or 'Subtitle'

matroskamux: Ignore some fields when renegotiating
...
Those values are never used in the muxer so we should not fail the
negotiation if those are changing.
