[esp32] Move heap functions to flash, saving ~6KB
...
This is the culmination of months of work to reduce heap churn
throughout the ESPHome codebase. By systematically eliminating
unnecessary dynamic allocations (StaticVector, FixedVector, const
char* instead of std::string, pre-allocated buffers, etc.), heap
functions are now called so infrequently that they can safely be
moved from IRAM to flash.
Enable CONFIG_HEAP_PLACE_FUNCTION_INTO_FLASH by default, which moves
malloc/free/realloc from IRAM to flash. This is safe because:
- Heap functions should never be called from ISRs
- CONFIG_SPI_MASTER_ISR_IN_IRAM is not enabled
- Audio/video use pre-allocated ring buffers, not dynamic allocation
Measured results: +6,124 bytes of heap freed.
Add heap_in_iram advanced option as an escape hatch for users who
need heap functions in IRAM for specific use cases.
