This standardizes selection tools in SELECTION_TOOL class to be able to
handle a long-click as asking for a non-heuristic disambiguation menu.

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.
CHANGED: Currently KiCad only checks for hotkey assignment conflicts
within the same program. However, if a hotkey is already assigned in
"common", it will also assign it to the specific program requested. When
the hotkey is pressed, the original asignment in "common" will take
precedence and it's action performed instead of the new action.
This MR looks for and detects hotkey assignment conflicts in both the
current program section and the "common" section.

Delete the copy ctor and assignment operator to start with, but
even then the separate apps each have their own statically allocated
copy of the common actions. So we need to update all of them, which
also means having the kicad manager frame's set of actions on hand).
This changelist also adds a Clear Hotkey Assignment function since
the hotkeys set is now likely to be sparse with respect to the
actions.
This separates the "ground truth" store of hotkeys from what is shown
in the dialog. This will allow us to filter the displayed hotkeys
while keeping the same underlying data structures.
Now, the UI data items interact with an intermediate set of data, which
represents the "original" hotkey data, and the "changed" data. The
ultimate aim here is to allow UI elements to come and go, but the
hotkeys that are "in-edit" are preserved.
This also allows us to abstract some bookkeeping complexity
out of the WIDGET_HOTKEY_LIST class into a separate non-GUI
class.
