Support extra methods/properties in SpatialQueryTestBase

[EricStG]

I'm adding new translations to npgsql/efcore.pg#457 and noticed that support in SpatialQueryTestBase was missing for some of them, namely:

• Geometry.Normalized()
• Geometry.ToGMLFeature()
• LinearRing.IsCCW

I'd like those methods and properties to be supported by the SpatialQueryTestBase class.

I can submit a PR if the project is open to those changes.

@EricStG Thanks, this would be great!

👍 Adding them to SpatialQueryTestBase is the right thing to do since it'll force other providers to think about whether or not they can be translated.

One question: How are you handling the XmlReader of ToGMLFeature()? Only translating it if it's chained with ReadOuterXml()?

NTS	MSSQL (geometry)	MSSQL (geography)	SpatiaLite
geometry.Normalized()	❌	❌	❌
geometry.ToGMLFeature()	❌	geometry.AsGml()	AsGml(geometry)
linearRing.IsCCW	❌	❌	❌

I'll admit I didn't think this far into my process... I just happened to be starting with the other ones and noticed they were missing, but it seems to make sense to only translate it if it's chained with ReadOuterXml(0.

Another possibility: #19991

@EricStG We discussed this and concluded that maybe you should try just Normalized and IsCCW since these don't have the XmlReader complications.

@ajcvickers Works for me, thanks!
