Don't return true with WiFiClientSecureBearSSL::connected() when really disconnected (#8330)

Browse Source 
* Don't return `true` with WiFiClientSecureBearSSL::connected() when disconnected

Apply the same condition as with normal WiFiClient - we are not connected
when it's not possible to both write and read.

Implement separate methods for actual connection status and the internal
ssl engine status and update methods that were previously using available()
for this purpose

Update examples to check available() when the intent is to only read the
data and not interact with the client in any other way. Also, use connect()
as a way to notify errors, no need to check things twice
