3b9ce6cb54 avfvideosrc: GL texture cache also supports YUY2 on macOS
BGRA gives black frames, and everything else fails to negotiate.

a8ed817d30 avfvideosrc: Use frame duration instead of frame rate
These days you're can use minFrameDuration and maxFrameDuration which
are CMTime with fractional values. That way we don't need to convert
between double and fractions in a really weird way.

This fixes really odd fractional values exposed in caps, like:

2000000/76923, 1000000/37037, 5000000/178571, 10000000/344827, 10000000/333333

Which are actually just 26/1, 27/1, 28/1, 29/1, 30/1

We can also delete a lot of outdated code for iOS versions older than
7.0 by using newer APIs.

855e86f6a2 avfvideosrc: Don't wait on main thread for permissions request
Recursively invoking the NSMainLoop can cause crashes in
applications that don't expect it. Instead of waiting for
permission to be granted, move the wait later - until we
actually need device permissions when starting the capture
session. That moves the wait into the streaming thread
instead of the application thread that's setting the pipeline
state to READY.

Instead of a manual state change implementation to open
and close the device, use the basesrc start/stop methods that
are intended for the purpose.

b3806da265 avfvideosrc: Report latency when doing screen capture
There is no `device` when doing screen capture, but there is always an
`input`, so use that to decide when we can reply to a latency query.
Without this, the latency query just fails.

0d72a6209c avfvideosrc: Fix wrong default framerate value
Current default G_MAXINT is not a correct value under any circumstances.
This creates an issue with screen capture, during which we currently do
not get any framerate info causing G_MAXINT to show up, where elements
downstream can possibly misbehave - for example, `vtenc` causes
a kernel panic.
Replace with 30/1 to avoid such scenarios.

acfc9ae216 avfvideosrc: fix wrong framerate selected for caps
This fix solves an issue where a format that doesn't support the
requested framerate would be selected. It ensures that we use the first
format and framerate pair that supports the requested caps.

d05fcadf4e applemedia: Document vtenc / vtdec elements
Also preserve-alpha property should only be exposed on the
vtenc_prores element since h264 does not support transparency.
