In the grey world AWB case, if no colour gains are contained in the
tuning file, the colour gains get reset to 1 when the colour temperature
is set manually. This is unexpected and undesirable. Allow the
gainsFromColourTemp() function to return a std::nullopt to handle that
case.
While at it, remove an unnecessary import from rkisp1/algorithms/awb.h.

Fix the top-level file description to mention the file contains an AWB
grey world implementation, not a base class, and fix a grammar mistake
in a documentation block.

Drop unneeded headers and add missing ones.
The yaml_parser.h header is dropped from awb_grey.h as the classes it
provides are only used in virtual functions defined by the base class,
so any required definitions are guaranteed to be available already.

The convention in libcamera is not to prefix getters with a 'get'
prefix. Rename the AwbStats::getRGBMeans() function accordingly.
