07165308f6 feat(heap): update hash map to use singly linked list
Previously, the hash map was a doubly linked list but was never
using the characteristics of it.

This commit switches the hash map to a singly linked list instead

This commit also fixes memory leak in heap trace tests by setting
hashmap size to 10 for the tests (instead of the default value of 250)

See https://github.com/espressif/esp-idf/issues/11173

6ce1ccd964 heap: Add trace configuration to allow hash map placement in external RAM bss section when possible
- Remove the size limit for the hash_map array from the CONFIG_HEAP_TRACE_HASH_MAP_SIZE
- Add test case for heap tracing using hashmap
- Update heap_debug.rst to document the newly added configurations in the heap component

Closes https://github.com/espressif/esp-idf/issues/11172

110aac240d heap: Add a configuration that places all the heap component and related functionalities in flash when enabled
Add test configuration to run all tests with heap component in the flash.
Add reference to this new configuration in performance section of the documentation.

bdfc348ab3 heap: Add trace hash map config
- and place all added functions and vairables related to the hashmap in RAM
when the config is enabled only.

- add number of hash map entry as a Kconfig value and remove the hash map init function.
This prevents the user from allocating the hash map in flash and pass the pointer to the
init function (as the heap trace manipulate the hash map from functions placed in IRAM).

- add max linear value to the KConfig to make it configurable by the users.

- protect access to static variable "tracing"

- remove unecessary field in heap_trace_hashmap_entry_t

2cf9236f6c heap trace standalone: Fix initialization of the unused linked list, update tests
- Call TAILQ_INSERT_TAIL in linked_list_setup to add unused records from the tail of the list
- Fix test "heap trace leak check" to expect that after a free, the record is zeroed instead of checking that
  the whole list of records is moved by one index in the array.
- Use esp_rom_printf() under lock instead of printf() since it does not rely on interrupts.

3737bf8322 heap: Remove TLSF related files and replace them with the tlsf submodule
As the tlsf implementation is a fork from https://github.com/mattconte/tlsf,
the sources are moved to a separate repository and used as a submodule in the esp-idf instead.

In this commit:
- Removing TLSF related files and using tlsf submodule instead.

- Adding components/heap/tlsf_platform.h header gathering all IDF specifics.

- The multi_heap_poisoning.c provides the declaration of the
function block_absorb_post_hook() definied weak in the TLSF repository.

- The tlsf_platform.h includes the tlsf_common.h file after the definition
of FL_INDEX_MAX_PLATFORM macro to make sure that this macro will be available
in tlsf_common.h without having to include tlaf_platform.h from IDF in the
tlsf_common.h header from the TLSF repository.

- Add missing include from tlsf_block_functions.h in the multi_heap.c file.
Change related to the changes made in TLSF repository (tlsf_block_functions.h
no longer included in tlsf.h)
