Jet can't candle a left join straight after a cross join. We have to push the cross join specifically down into its own subquery and then do a left join on that

Introduce a new typed JetConnectionStringBuilder
...
This makes it easier to use than the extensions (EntityFrameworkCore.Jet.Data.DbConnectionStringBuilderExtensions) with Get/Set methods.
With the new `JetConnectionStringBuilder` class:
```csharp
var csb = new JetConnectionStringBuilder(DataAccessProviderType.OleDb)
{
Provider = "Microsoft.ACE.OLEDB.12.0",
DataSource = @"C:\myFolder\myAccessFile.accdb",
DatabasePassword = "hunter2",
};
var connectionString = csb.ConnectionString;
```
Without the new `JetConnectionStringBuilder` class:
```csharp
var csb = new OleDbConnectionStringBuilder();
csb.SetProvider("Microsoft.ACE.OLEDB.12.0");
csb.SetDataSource(@"C:\myFolder\myAccessFile.accdb");
csb.SetDatabasePassword("hunter2");
var connectionString = csb.ConnectionString;
```

Make EntityFrameworkCore.Jet available on `net6.0`

Make EntityFrameworkCore.Jet available on `net6.0`
...
By using `[SupportedOSPlatform("windows")]` at assembly level instead of targeting `net6.0-windows`.
This will enable taking a dependency on the EntityFrameworkCore.Jet* NuGet packages on Linux and macOS. The consumer of EntityFrameworkCore.Jet can then decide how to handle [CA1416][1] either by adding `[SupportedOSPlatform("windows")]`, by targeting `net6.0-windows` or by testing `OperatingSystem.IsWindows()` at runtime.

Do the same clr type check when mapping "text" as what we do for other store type mappings. This allows conversions do work better (e.g. originally a mappingInfo with a System.Char type was passed in with store type of "text" and a variable length or unbounded string type was returned but with clr type of System.String. Going with the extra checked returns null and gets EF Core to find a converter and then do the mapping again on the converted type

When dealing with convert, if we don't have a specific conversion function, try just send the original operand and let Jet work with the types. Seems to be fairly lenient

MID doesn't allow a null value for the length parameter. Add a IIF wrapper around it if that argument is marked as nullable.
...
Added here instead of stringmethodtranslator as we need the nullability optimizations on the sqlfunctionexpression. When wrapped in a caseexpression we get some different optimizations. Produces the correct result on the test case but is different to SQL Server. This way we keep it closer to SQL Server
