Fixes #10209

Fix #10232

From #10204 by @adriancuzman

- And implement the `backtrace()` function call

The `_O2` attribute is no longer needed on the malyanlcd function, and the macros have broken timer numbers - reset this to a function to return the right device. Also fix the bit order cast in SPI.

From #10234 by @thopiekar

[2.0.x] DUE: Several fixes to the backtracker

Added some missing Thumb instructions to the traceback follower, so now it is able to traceback through switch() statements

Based on #10216

Tons of fixes to the backtracker code, and also added an extra backtracker that does not require unwind tables to work and it is used if unwind tables are absent

[2.0.x] DUE debugging: Solve WDT startup delay, add traceback & crash report uses programming port baud rate
