[SqlClient] Rename Enrich property

[martincostello]

Fixes #3074

Changes

Renames the Enrich property to EnrichWithSqlCommand and removes the custom event name parameter.

The parameter remains an object so it is compatible with both System.Data.SqlClient and Microsoft.Data.SqlClient.

Builds on top of #3079.

Merge requirement checklist
