Some date and time updates

- Don't derive Timespan and DateTimeOffset type mapping from our JetDateTimeTypeMapping. We can derive from the normal base class for those types
- DateTimeOffset is now mapped to a string. This allows us to round-trip all the details, however any calculations or queries for any components do not work

Convert a null constant in a projection to a variant. We only do this if the type is meant to be a numeric. This is because NULL on its own has some issues when unioning with int values. Some joins with this issue were fixed in an earlier commit

The default value for DateTime in Jet is 30/12/1899 . When we save if we get a 1/1/001 we translate to this value. When reading we need to do the reverse translation

Add our own GearsOfWar set of base classes and models. This allows us to modify it so that we can work around the complex/multi-field foreign key set up it uses so that we can use our own Match Simple mode rather than the Match Full mode Jet normally does.

UNIONing projection with a numeric column to another projection that specifically projects NULL the the same name as a numeric field, the JOINING that to another table can leave that numeric field as another data type (NULL is not a numeric data type). Hence when using that supposedly numeric field in the join predicat against another numeric field we get a data type mismatch.
...
We try to detect this and when visiting the column (but only if we are within a binary expression and not a projection) we quickly wrap it in a convert function to make it properly numeric
The top/outer projection of this field can still be in a non numeric format, but JetDataReader is able to handle that. Would be better to produce the correctly converted data output anyway

Rewrite some INNER JOIN's. According to the docs Jet doesn't support an INNER JOIN being nested under a LEFT JOIN. We try to figure out which one's they are and rewrite it. As an INNER JOIN is a join where both sides have a value, we can rewrite it as a LEFT JOIN and then filter out the rows where the columns the join is on is not NULL

Set query splitting behaviour. Prevents errors due to it not being set

Set CanExecuteQueryString to false. When running tests, if it is set to true, the Query Asserter will also try to create a query string from the IQueryable. While most cases are fine, the problem comes in when there are parameters. Creating the query string declares the parameters and values at the beginning of the query and the DbCommand is set up with no parameters. While this can work in Sql Server (see the DECLARE keyword), this is not supported with Jet.
...
The Query Asserter already runs the CreateDbCommand on the IQueryable which creates the DbCommand with the parameters all set up. Creating the query string and running that as a separate command is not really necessary.
By the looks of it this only affects the test system which specifically creates a query string from an IQueryable and creates a new DbCommand with that as the command text. It doesn't seem to affect anywhere else
