Vanilla FreeRTOS expects applications to use one of the heap implementations provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc() and vPortFree() are defined in the heap implementation. However, ESP-IDF already provides its own heap implementation (i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were previously overriden by macro to call esp_heap functions directly. This commit refactors the FreeRTOS port's heap as such: - Added a heap_idf.c that implements all of the heap related functions required by FreeRTOS source - All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the FreeRTOS heap is the internal memory subset of the ESP-IDF heap. - Removed some old macros to reduce diff from upstream source code.
