Deprecate SPIFFS, move examples to LittleFS (#7263)
* Deprecate SPIFFS, move examples to LittleFS

SPIFFS has been a great filesystem, but it has significant problems in
many cases (and it's also pretty slow).  Development seems to have
slowed/stopped on the upstream version, and we're not able to provide
support or fix the known issues with it as-is.

Deprecate SPIFFS variable.

Update all examples to use LittleFS instead of SPIFFS.

Also, minor cleanup on very old examples which has obsolete delays
waiting for the Serial port to come up, or which were stuck at 9600 baud
because of their ancient AVR heritage.

Fixes #7095

* Remove leftover debug code

* Clean up comments in some examples

* Update documentation on SPIFFS deprecation

* Fix host tests to avoid deprecation warnings

* Fix cut-n-paste error

* Restore SpeedTest.ino, adjust to allow custom FSes
