# Description
The idea behind this PR is to make it easier for the users to tweak
filament setting overrides i.e. reduce number of times users have to
switch between the printer and filament settings to compare the values.

## Tests
I've done some manual testing to confirm:
* Override setting with the same value as extruder is still shown as a
change.
* Resetting unsaved override setting back to original value still works
as expected.
* Override settings are shown correctly on the next load after a save.
* Extruder settings changes are reflected on Settings Overrides page.
## Other
I have discovered a strange behaviour between `Filament Settings` and
`Printer Settings` windows. On a fresh load of application opening
`Filament Settings` window, navigating to `Settings Overrides` tab and
then closing the window results in `Filament` tab being opened the next
time `Filament Settings` window is opened. But if you open `Printer
settings` window, navigate to `Extruder` or `Motion ability` tabs then
the application changes the behaviour to open the last visited tab by
the user for both of the windows. I'm mentioning this because when this
happens the flow of events in the application changes and causes my
change to break until the user changes a tab. As far as I can tell for
some reason ConfigOptionsGroup's `reload_config` method is starting to
get called (second time?) after TabFilament's
`update_filament_overrides_page` method which wipes out the values set
by me. I'm not sure which is the correct behaviour, so I left that for a
discussion here. If last visited tab is the correct behaviour, then I
would need help to figure out how to fix this problem.
This PR moves the code around without any functional changes, so that all code related to supports now placed at the same location & structure as BambuStudio.
This makes merging updates from BambuStudio much easier in the future.

# Description
This update, along with #6934, resolves the remaining issues with the
wipe tower.
The GCode class will no longer maintain its own Z height information
(m_nominal_z). Instead, it will utilize the Z height from GCodeWriter's
m_pos. This approach is less error-prone.
This PR also fixes#6755.
It also enforce "Enable Filament ramming" option
@igiannakas It should fix the wipe tower crashing issue
