ffmpeg: update to ffmpeg-9.0.1 [skip ci] [ci skip] [no ci]

Testing the changes

• I tested the changes in this PR: briefly

[skip ci] [ci skip] [no ci]

see previous ffmpeg8 PR #58253

If someone else test, could you verify if mlt7 picks up libavdevice8 ? It didn't install for me but I assume it may have been due to upgrading from ffmpeg8 branch instead of current repos and manually installing some packages.

========== libmltavformat.so ============
	linux-vdso.so.1 (0x00007f0322790000)
	libmlt-7.so.7 => /usr/lib/libmlt-7.so.7 (0x00007f03226e8000)
	libavcodec.so.62 => /usr/lib/libavcodec.so.62 (0x00007f0320d8f000)
	libavfilter.so.11 => /usr/lib/libavfilter.so.11 (0x00007f032078f000)
	libavdevice.so.62 => not found

New package

• This new package conforms to the package requirements: YES

• sse2neon - it's just a header file, it's either that or kick around a 11k line file for blender

• ffmpeg8 - should be removed, gmic is only outstanding package

Local build testing

• I built this PR locally for my native architecture, x86_64
• I built this PR locally for these architectures (if supported. mark crossbuilds):
  • tbd

ffmpeg4

closes #51522

• cmus - patch for latest git, still waiting for release
• ssr - use git commit, still waiting for release
• kodi - use internal ffmpeg6, this is never quick to update and will always lag behind

everything else, including vlc, can build with 8 or 9.

ffmpeg8

could probably get rid of 8 altogether with blender 5.2 and opencv5 #62568

gmic is only outstanding issue.

opencv (gmic)

   ---synfig
---retroshare

---gpac (arch has patch)
---ccextractor
---cyanrip
---fooyin (builds with 9)
---gifski (rust crate currently 9.0.0 i think)
---kid3 (builds with 9)
---hedgewars (will need manual patch, maybe 1.0.3 works? --- arch has 1.0.3 patch)
---retroarch
---ssr
---wf-recorder (arch has patch)
---qt5-webengine (can test 9, qt6-pdf works)

blender 5.2.2 update

per closed PR #62585

5.2 is seemingly for ffmpeg7+ (or 8?) - just going to roll into ffmpeg9 since there are no available patches and downpatching for some mid-way step that is just going to be immediately built for ffmpeg9 seems like a waste of time.

• aarch64 simd

compiles but did not test. could probably just add openimagedenoise to makedeps ? this only works on x86_64 and arm64. i don't think ppc is still officially supported or used.

• openimagedenoise redirects to renderkit on github now
