[socket] Implement working ready() for LWIP raw TCP sockets (ESP8266/RP2040)

Previously ready() always returned true on ESP8266/RP2040, causing
every socket to be checked on every loop iteration even when no data
was available.

Override ready() in LWIPRawImpl to check rx_buf_/rx_closed_/pcb_ state,
and in LWIPRawListenImpl to check accepted_socket_count_. This uses
existing fields so no extra memory is needed per socket.

Keep ready() virtual only on the non-select path (ESP8266/RP2040) so
the select()-based path (ESP32) retains the non-virtual optimization
from the previous commit.

+ * Chunked responses that complete in a reasonable time work correctly on both
+ * platforms. The limitation below applies only to *streaming* chunked
+ * responses where data arrives slowly over a long period.
+ *
+ * Streaming chunked responses are NOT supported (all platforms):
+ *   The read helpers (http_read_loop_result, http_read_fully) block the main
+ *   event loop until all response data is received. For streaming responses
+ *   where data trickles in slowly (e.g., TTS streaming via ffmpeg proxy),
+ *   this starves the event loop on both ESP-IDF and Arduino. If data arrives
+ *   just often enough to avoid the caller's timeout, the loop runs
+ *   indefinitely. If data stops entirely, ESP-IDF fails with
+ *   -ESP_ERR_HTTP_EAGAIN (transport timeout) while Arduino spins with
+ *   delay(1) until the caller's timeout fires. Supporting streaming requires
+ *   a non-blocking incremental read pattern that yields back to the event
+ *   loop between chunks. Components that need streaming should use
+ *   esp_http_client directly on a separate FreeRTOS task with
+ *   esp_http_client_is_complete_data_received() for completion detection
+ *   (see audio_reader.cpp for an example).
+ *
+ * Chunked transfer encoding - platform differences:
+ *   - ESP-IDF HttpContainer:
+ *       HttpContainerIDF overrides is_read_complete() to call
+ *       esp_http_client_is_complete_data_received(), which is the
+ *       authoritative completion check for both chunked and non-chunked
+ *       transfers. When esp_http_client_read() returns 0 for a completed
+ *       chunked response, read() returns 0 and is_read_complete() returns
+ *       true, so callers get COMPLETE from http_read_loop_result().
+ *
+ *   - Arduino HttpContainer:
+ *       Chunked responses are decoded internally (see
+ *       HttpContainerArduino::read_chunked_()). When the final chunk arrives,
+ *       is_chunked_ is cleared and content_length is set to bytes_read_.
+ *       Completion is then detected via is_read_complete(), and a subsequent
+ *       read() returns 0 to indicate "all content read" (not
+ *       HTTP_ERROR_CONNECTION_CLOSED).
+ *
  * Use the helper functions below instead of checking return values directly:
