Port EditGCodeDialog from PrusaSlicer (#3417)

This is a port of the EditGCodeDialog from PrusaSlicer 2.7.x. There were
a few changes made to make it a bit more functional. Also, it isn't
quite fully complete, but it should be in a very usable state.

General Changes:
- Implement UndoValueUIManager and EditValueUI in Field
- Implement EditGCodeDialog and add buttons to the tabs
- Other minor changes to accommodate the new classes

Differences from PrusaSlicer's Implementation:
- backported to wxWidgets 3.1.5 (reverse commit 8770c4b7 after updating
to 3.2.x)
- icons have been updated to use Orca colors
- improve the report that tells you if certain placeholders have not
been defined properly for the dialog. It now shows all issues at once
rather than having to fix then recompile to see the next issue.
- allow the use of the cmake option `ORCA_CHECK_GCODE_PLACEHOLDERS` to
toggle the above report since our workflow rarely uses debug mode.
- if a custom gcode value is not set when checking gcode placeholders, a
testing value is set. Custom gcode is not parsed if it is empty, and the
only way to check if the placeholders are all defined is by running the
placeholder operation on the custom gcode.
- some calls to `print.config()` in Gcode.cpp were changed to `m_config`
to support the above testing values feature (only m_config is modified
with the placeholders and `print.config()` would return an empty string)
- a macro has been added to quickly add a definition to
SlicingStatesConfigDefs with less boiler plate (it could technically be
used for any ConfigOptionDef, but that would hurt interoperability with
PS. I tried to not use the macro for too many PS defined definitions.)
- the presets are now also categorized by the page they are on in their
tab

TODO:
- [x] Make sure all linux fixes have been applied
- [x] Finish adding "universal" gcode options
- [x] add search function to dataview (maybe?)
- [x] determine if any options are being left out of the preset
categories by getting options from Tab rather than Presets. If so,
consider adding outside of the groupings
