Partially undo 15357af to ensure TMC code is initialized in the proper order.

…And save backlash, fil. sensor, ExtUI userdata to EEPROM.

- Remove a re-paint of the status screen on stepper timeout, which would cause a garbled LCD with `LIGHTWEIGHT_UI` and could interrupt whatever else the user might be doing in a submenu (such as playing games!)
- Use the helper function to reset stepper timeout.

Allow `ENABLED`, `DISABLED`, `PIN_EXISTS`, and `BUTTON_EXISTS` to take multiple arguments. Also add:
- Alias `ANY(...)` for `!DISABLED(...)`
- Alias `ANY_PIN(...)` for `PIN_EXISTS(a) || PIN_EXISTS(b) ...`
- Alias `EITHER(A,B)` for `ANY(...)`
- Alias `ALL(...)` and `BOTH(A,B)` for `ENABLED(...)`
- `NONE(...)` for `DISABLED(...)`

- Send notifications to ExtUI for M0/M1

- wait_for_user can be non-volatile (not changed by interrupt)
  C / C++ compilers don't optimize away reads of non-volatile variables when a function call is used between accesses, because *any* variable could be changed by the function call. Since `wait_for_user` can't be changed without a function call, it should be non-volatile so the compiler can optimize away cases where it is read more than once without an intervening function call.

Fix #13184

Observing from the console, it makes the most sense to do `//action:probe_retry` before executing commands.

- Fix compile error when accessing `process_subcommands_now_P`.
- Use `const` var eliminating double-negative (to make code more understandable).

* Make CardReader a static class
* Make CardReader flags into bitfields

* Encapsulate common LCD code in a singleton
* Depend more UBL code on UBL_DEVEL_DEBUGGING
  - Since most users don't need the debugging on at all times, this helps reduce the default build size for UBL by over 2K, a little closer to fitting on 128K boards.

* Followup to LCD_TIMEOUT_TO_STATUS=0
* Make continuous purge screen fit 20x4
* Unify purge message modes
* Preserve last-set pause header mode
