Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
on gcc 12.1 / msys2 the large initialized list in bitmap_info.cpp breaks
the compiler (perhaps a bug in the compiler).
So, as workaround, the initialization sequence is modified.
The main purpose is to make changes in g_BitmapInfo more easy.
Although it is automatically generated, it is sometime more easy to modify
it by hand (the recreation of bitmaps stuff is time consumming), especially
during testing.
Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.

This allows for color changes and scaling of the arrow
when the display needs it (e.g. HiDPI displays).
Also make the arrow and text respond to if the window is
active to mimic native controls.

Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
