xtensa linker throws warning
dangerous relocation: windowed longcall crosses 1GB boundary; return may fail
create separate function to call function by pointer to avoid warnings
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.

Updated S3 to use PMS protection for writing to flash through cache. This means we get
a panic quicker for this illegal behavior than we did before, making the source of the error
easier to track down.
Before this change _invalid_pc_placeholder pointed to address of _init
function from crti.o
This made GDB input a bit confusing:
0x40080400 in _init ()
(gdb) bt
#0 0x40080400 in _init ()
#1 0x400e519a in test_instr_fetch_prohibited () at /home/alex/git/esp-idf/tools/test_apps/system/panic/main/test_panic.c:271

After the change GDB prints output that contains a hint:
_invalid_pc_placeholder () at /home/alex/git/esp-idf/components/xtensa/xtensa_vectors.S:2235
2235 UNREACHABLE_INSTRUCTION_CHECK_PREVIOUS_FRAMES

This feature is useful for 3rd-party software to run GDB with predefined
options that described in project_description.json file
allow to pass custom options to "idf.py gdb":
--gdb-commands: command line arguments for gdb. (without changes)
-ex: pass command to gdb.
-x: pass gdbinit file to gdb. Alias for old --gdbinit command
The default newlib read/write syscalls automatically convert newline
endings from LF to CRLF on stdout. Therefore, the test should not
specifically check for LF in the expected output, as the standard
conversion for stdout is CRLF. While it is possible to change the
expected line ending in the test from LF to CRLF, it seems more
dependable to just avoid verifying line endings entirely.
