This commit updates the following:
- Updates the panic handler to use only the RTC WDT to reset the system.
- Refactors some of the panic handler code.
- Updates Bluetooth files where in they now feed the WDTs instead of
reconfiguring them.
- Removes some unnecessary configuration of WDTs from various files.
- Added a unit test to verify that the system does not lock up when the
panic handler is stuck.
- Updates the memprot unit tests to work with the refactored panic
handler.

This commit deprecates the "freertos/xtensa_context.h" and "xtensa/xtensa_context.h"
include paths. Users should use "xtensa_context.h" instead.
- Replace legacy include paths
- Removed some unnecessary includes of "xtensa_api.h"
- Add warning to compatibility header
- Add support for esp32s2, esp32c3 and esp32c2 for the `memprot`-related tests
- Preliminary support for esp32s3 has also been added,
the test app will be enabled for esp32s3 later when
the memprot-related issues are fixed.
- Override panic handler to dump the violation intr status
- Dump the `memprot` violation registers before calling the
real panic handler
- Handle `Illegal Instruction` exception in case of memprot permission violation
* In esp32c3 with `memprot` enabled, if we try to execute arbitrary code
from RTC_FAST_MEM we get an `Illegal Instruction` exception from the panic
handler rather than a `Memory Protection Fault`.
* This is because the Illegal Instruction interrupt occurs earlier than the
memory protection interrupt due to a higher interrupt latency.
