libcamera: bayer_format: Remove unnecessary constructor

Browse Source 
The new `fromV4l2PixelFormat` static member function renders an old
BayerFormat constructor useless, remove it together with the
`v4l2ToBayer` mapping table. The new function searches for a matching
mapped value instead of a matching key, therefore the `bayerToV4l2`
table is sufficient.
