Quote when adding to connection string in (PDO_)ODBC
Because the UID= and PWD= values are appended to the SQLDriverConnect
case when credentials are passed, we have to append them to the string
in case users are relying on this behaviour. However, they must be
quoted, or the arguments will be invalid (or possibly more injected).
This means users had to quote arguments or append credentials to the raw
connection string themselves.

It seems that ODBC quoting rules are consistent enough (and that
Microsoft trusts them enough to encode into the .NET BCL) that we can
actually check if the string is already quoted (in case a user is
already quoting because of this not being fixed), and if not, apply the
appropriate ODBC quoting rules.

This is because the code exists in main/, and are shared between
both ODBC extensions, so it doesn't make sense for it to only exist
in one or the other. There may be a better spot for it.

Closes GH-8307.
