fixed G10 and G92 offsets

[Paciente8159]

• fixed G10 offset when G91 is active and ignoring G92 coordinates
• fixed G92 calculations relative to current coordinate system
• making non modal commands sync (except G53) to prevent coordinate WCO to be applied ahead of time

Thanks, i've had a go with this, and G10 seems to behave as I'd expect now.

I'm not sure about G92 though. I've never used that before, but it seems to behave strangely.

The new g92_offset calculation looks right if target is the raw value provided in the command, but this offset is still applied:

uCNC/uCNC/src/core/parser.c

Line 1677 in f0afb7b

target[i] += parser_parameters.coord_system_offset[i] + parser_parameters.g92_offset[i];

It also seems like the g92_offset calculation is always applied to all axes, but it should only be applied to specified ones.

When i work around those issues it seems to work, though i'm not sure what the behaviour of G10 L20 should be in the presence of a g92 offset.

Has I said in #790 the G10 L20 will also be affected by G92.

I will test G92 to see if that is the case that is modified also for non declared ox explicit axis values.

Works great, thank you!
