enable ffmpeg native h26x software decoders for all platforms (#7750)

* enable ffmpeg native h26x software decoders for all platforms

* h26x software decoders depend on hwcodec feature, so all platforms
  enable it, software h26x decoders are always available like vpx, no available check and no option
* ffmpeg:
	- build: mac arm64 build ffmpeg with my m1, others build with ci
	- version: win/linux use ffmpeg release/5.1, becaues higher version require higher nvidia driver,  other platforms use release/7.0
* test:
	- ios not test.
	- android: sometimes the screen will appear blurry, but it will recover after a while.
	- arm64 linux: test a example of hwcodec repo
