iabdalkader 90bd11e937 common: Refactor TinyUSB debug interface implementation.
This commit refactors the TinyUSB debug interface with the following changes:

- Handle disabled IRQs.
- Replace global variables with centralized state.
- Add timeout, and validation for more robust transfers (as much as possible
  given the protocol limits).
- Remove obsolete/unsupported commands (attr read/write, script save etc..)
