psram: make SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY configurable on S2 and S3 

SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY was always enabled on S2 and S3, but this option is not
compatible with ESP_COREDUMP_ENABLE_TO_FLASH. Make it configurable to allow users to deactive
it so that ESP_COREDUMP_ENABLE_TO_FLASH can be used.

Accessing memory in SPIRAM has certain restrictions, so task stacks allocated by xTaskCreate
are by default allocated from internal RAM.
This option allows for passing memory allocated from SPIRAM to be passed to xTaskCreateStatic.
This should only be used for tasks where the stack is never accessed while the cache is disabled.
Cannot be used together with ESP_COREDUMP_ENABLE_TO_FLASH.
