BREAKING: Add Print::availableForWrite method (#7658)

Browse Source 
* Add Print::availableForWrite method

Adds an availableForWrite() method to the Print class, matching current
ArduinoCore-API commit 398e70f188e2b861c10d9ffe5e2bfcb6a4a4f489 .

Hook availableForWrite into the SDFS filesystem (other FSes don't have
this capability built-in).

Fixes #7650

* WiFiClient::availableForWrite proto matching Print

* Fix Netdump signedness warning

* Clean up Serial availableForWrite

This is evidently a breaking change due to the type difference.
Arduino's `availableForWrite` returns an `int`, while the
(multiply-implemented, non-virtual) core `availableForWrite` returned
`size_t`.
