esp32: Update to use ESP-IDF v5.4.2.

Browse source 
This is a patch release of the IDF.  Comparing with 5.4.1, firmware size is
up by about 1.5k on ESP32 and 9k on ESP32-S3.  But IRAM usage (of the IDF)
is down by about 500 byte on ESP32 and DRAM usage is down by about 20k on
ESP32 and 10k on ESP32-S3.

Testing on ESP32, ESP32-S2, ESP32-S3 and ESP32-C3 shows no regressions,
except in BLE MTU ordering (the MTU exchange event occuring before the
connect event).
