libcamera: CameraSensorProperties: Add table of v4l2 index and test pattern

Browse Source 
The V4L2 specification defines the sensor test pattern modes
through a menu control, where a numerical index is associated to
a string that describes the test pattern. The index-to-pattern
mapping is driver specific and requires a corresponding representation
in the library.

Add to the static list of CameraSensorProperties a map of indexes to
libcamera::controls::TestPatternModes values to be able to map the
indexes returned by the driver to the corresponding test pattern mode.
