Fixed memory leak in emac_esp_new_dma function.
Polished ESP EMAC cache management.
Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO
initialization.
Added ESP EMAC GPIO reservation.
Added check for frame error condition indicated by EMAC DMA and created a target test.
This commit adds support for handling multiple requests simultaneously by introducing two new functions: `httpd_req_async_handler_begin()` and `httpd_req_async_handler_complete()`. These functions allow creating an asynchronous copy of a request that can be used on a separate thread and marking the asynchronous request as completed, respectively.
Additionally, a new flag `for_async_req` has been added to the `httpd_sess_t` struct to indicate if a socket is being used for an asynchronous request and should not be purged from the LRU cache.
An example have been added to demonstrate the usage of these new functions.
