Vector support for bulk copy

[MaceWindu]

Software versions
MySqlConnector version: 2.5.0-beta.1

Describe the bug

Trying to add float[] value results in

System.NotSupportedException: 'Type Single[] not currently supported. Value: System.Single[]'

As workaround, conversion to byte[] could be used

Exception

System.NotSupportedException
  HResult=0x80131515
  Message=Type Single[] not currently supported. Value: System.Single[]
  Source=MySqlConnector
  StackTrace:
   at MySqlConnector.MySqlBulkCopy.<SendDataReaderAsync>g__WriteValue|32_0(MySqlConnection connection, Object value, Int32& inputIndex, Encoder& utf8Encoder, Span`1 output, Int32& bytesWritten) in /_/src/MySqlConnector/MySqlBulkCopy.cs:line 597

Update: workaround works with MariaDb, but not with MySql:

MySqlConnector.MySqlException
  HResult=0x80004005
  Message=Value of type 'string, size: 16' cannot be converted to 'vector' type.
  Source=MySqlConnector

What's the user scenario? Copying a table with a VECTOR column? (I assume you can't use INSERT INTO ... SELECT ... FROM?)

[MaceWindu]

It's ORM tests for type mappings to work with all supported operations.

[MaceWindu]

Specific test scenario is to populate table from client data using provider's bulk copy functionality

Thanks for the suggestion; this should probably have been included in #1551.

Fixed in master if you're able to build and test the latest source code.
