MDEV-31608 - Connector/NET fails to connect since 10.10

Browse Source 
Connector/NET does not expect collation IDs returned by "show collations"
to be NULL, runs into an exception.

The fix is to determine connector/net using its connection attributes,
then make sure "show collations" does not output NULL IDs.

The patch introduces new old_mode NO_NULL_COLLATION_IDs, that is
automatically set, once MySQL Connector/NET connection is determined.

A test was added, that uses MySql.Data from powershell - only works
if MySql.Data is installed into GAC (i.e with C/NET MSI package)
