A number of regressions were patched also. The UBL G29 P2 and P4 Press and Hold had stopped working. It is very possible this is broken in the bugfix_v1.1.x branch also.

The main purpose of the Pull Request is to get the 3-Point mesh tilting to use the LSF algorithm just like the grid based mesh tilt. This simplifies the logic and reduces the code size some what. But the real reason to do it is the 3-Point case can be solved exactly. And by feeding these numbers into the LSF algorithm it provides a way to check all that code for 'correctness'.

Fix #9155

Followup to #8148

Some also get a `HAL_timer_interrupt_enabled` function.

This will save some program memory with no speed lose

It seems that some SD cards don't support CRC_ON_OFF command. This fix will permit to use also these cards but leaving CRC check active on the system

* Update persistent_store_impl.cpp
* Remove define BYTE from serial functions since Arduino docs typically show 0 for the normal case.

WORKS!
