Update IDF to 90747cc8b (#3118)

* Fix persistance issue found, see ESP8266 issue #6152

* Correcting the parsing of the header for HTTP1.0

* Send 'Connection: Close' header in case of HTTP1.0

* Let reuse connection depend on protocol used: HTTP1.0 or HTTP1.1

* Fixed reuse, added null ptr checks, added check for _trainsportTraits in connect() in case _client was set null

* Fix reuse connection issues, similar to ESP8266 PR #6176

+Most of the framework is implemented. Most noticeable is the missing analogWrite. While analogWrite is on it's way, there are a few other options that you can use:
 - 16 channels [LEDC](cores/esp32/esp32-hal-ledc.h) which is PWM
 - 8 channels [SigmaDelta](cores/esp32/esp32-hal-sigmadelta.h) which uses SigmaDelta modulation
 - 2 channels [DAC](cores/esp32/esp32-hal-dac.h) which gives real analog output
