Removes the ability to hide symbol units in file formats. This was
mostly the case for a while but there remained corner cases where we
left a default/hidden option

(cherry picked from commit 8c36ba3653)
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
It's tempting to say that we don't need to exclude filename chars
from symbols, but we might regret that decision down the road. Better
to just escape them.

1) Don't reset value when name changes
2) Don't fire events when initialising dialog
3) Make sure when symbol is saved back to schematic that only current
instance has its ref updated, but that all instances have their other
fields updated.
4) When saving symbol back to board always use the fields from the
editor and not the (alias-specific) ones from the library.

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.
