Since SPI flash operations can not be performed when the stack is in
external RAM, we need to switch to a different stack when doing a
core dump to flash. This is achieved by a pair of longjmp's, one of
which is crafted manually to jump into a designated function with a
specific stack set up.
The cost of this feature is a bit of IRAM, plus the DRAM required for
the extra stack.
Closes AUD-1355
remove duplicated include from components/esp32/incliude/esp_core_dump.h
espcoredump/incliude/esp_core_dump.h:
fix signature of the functions esp_core_dump_to_uart() and esp_core_dump_to_uart();
add espcoredump into COMPONENT_PRIV_REQUIRES list
fix linker.lf file
Move existing core dump files into espcoredump component folder
Add KConfig, linker.lf, make and CMakeList.txt for new component
Existing functionality separated into core_dump_common, core_dump_flash, core_dump_uart
Update test_core_dump.c and make files to link it as unit test
Update according to review:
Move target and RTOS related functionality into separated file (core_dump_port.c).
