Really nice to be seeing proper async/await in SqlClient!

This introduces async-over-sync, removing such requires work with the state machine and separate review.

@edwardneal - Can you resolve the conflicts, and then I will kick off another CI run? |

Remove SqlDataReader.GetSchemaTableAsync (and references to such.) Expand test coverage of both GetSchema and GetSchemaAsync. Correct typo in documentation for GetSchema and GetSchemaAsync.

I've updated this branch after the SqlConnection merges were applied, could I have a CI run please? |

Contributes to #646, adding
SqlConnection.GetSchemaAsync.I can't add the IDbColumnSchemaGenerator method because the .NET Framework version of SqlDataReader doesn't yet implement that interface. #2967 tracks this.
SqlDataReader.GetSchemaTableAsyncrequires some extra work with the state machine to guarantee that the column metadata is available, and I'll submit a separate PR for this.I've added some basic documentation, but this effectively follows the
SqlCommand.[Something]Asyncpattern of "An asynchronous version of [Something], which <etc.>"I've also moved the netfx GetSchema methods from SqlConnectionHelper.cs to SqlConnection.cs, to align that part of it with netcore. This contributes to the merge slightly.
