048628083a Remove clear_current_adv_vars() 
The pressure state is already reset implicitly at the end of each block,
meaning an extruder switch will never have to reset the internal state
anyway.

We clear the internal backpressure in the following conditions:

- when switching to a non-LA block
- when quickStop is called
- when the scheduler is idling (losing pressure)

7d33089d9a Remove use_advance_lead 
The per-step state is kept implicitly using nextAdvanceISR,
while the current pressure is decoupled anyway.

1bed8cfa94 Don't call fsensor_st_next_block repeatedly during the last step 
Rely on st_block_begin to perform a single call instead of calling
block_chunk for each advance tick in the last step

84009e1e8e Do a full fsensor_update() when initializing the sensor 
This correctly populates the "extruder info" details even when
the menu is entered for the first time after starting a print.

fa7c0fb2c9 Avoid triggering LA during a Z-priming move 
When recovering from a pause, the nozzle is often primed while
being lowered. If LA is triggered under such a move, the pressure
advance will be wasted.

c50b1c0351 Rework the filament counter logic 
- Move direction checks out of fsensor: fsensor_counter is now
  always in the same direction as e_steps
- Check the filament chunk after e_steps have been physically done,
  using the real e_step count so far

cbf1a85ec3 Switch original LA implementation with LA1.5

We'll re-implement those later if needed.
