The ISI pipeline handler currently associates the output PixelFormat with the
media bus code that can produce it. This mapping is however limiting as
the ISI can produce any YUV/RGB format from any non-RAW media bus format.

Rework the format selection procedures in order to remove the association
between pixel formats and mbus codes by introducing 4 new functions.

This fixes the problem originally pointed out by Laurent that when used with
RAW sensors, the generated CameraConfiguration does not work as it assumes a
YUV media bus code is available.

Tested with ov5640 which can produce UYVY8, RGB565 and SBGGR8.

	$ cam -c1
	Selected sensor format: 1920x1080-UYVY8_1X16

	$ cam -c1 --stream role=raw
	Selected sensor format: 2592x1944-SBGGR8_1X8

	$ cam -c1 --stream pixelformat=RGB565
	Selected sensor format: 1920x1080-RGB565_

Tested with imx219 which can only produce SRGGB10

	$ cam -c1
	Selected sensor format: 3280x2464-SRGGB10_1X10

	$ cam -c1 --stream pixelformat=YUV
	WARN ISI imx8-isi.cpp:278 Cannot find a supported YUV/RGB format

	$ cam -c1 --stream role=viewfinder
	Selected sensor format: 3280x2464-SRGGB10_1X10

Also fix the available stream formats list for both YUV and RAW use cases.
