## Summary This PR intends to enable the separation of Kernel and Userspace heaps in ESP32S3 operating under Flat mode. This new feature enables the allocation of the entire Userspace heap into SPI RAM and reserving the Internal RAM exclusively for the Kernel heap, which may benefit some timing-constrained Kernel components (e.g. Wi-Fi driver). ## Impact ## Testing * Successful execution of ostest in `esp32s3-devkit:psram_usrheap` defconfig. * Successful connection to Wi-Fi network using a custom version of `esp32s3-devkit:wapi` and enable SPIRAM config: `CONFIG_ESP32S3_SPIRAM/CONFIG_ESP32S3_SPIRAM_USER_HEAP/CONFIG_XTENSA_IMEM_USE_SEPARATE_HEAP`  -- This is an automated message from the Apache Git Service.
