Pull request overview
This PR improves NativeAOT compatibility for compiled models by avoiding reflective creation of default value comparers/converters, and by making type mappings generic where the model CLR type is statically known.
Changes:
- Add generic type-mapping base types (
CoreTypeMapping<T>,RelationalTypeMapping<T>) and update built-in relational mappings to derive from them, enabling non-reflective default comparer creation. - Add cached default instances for common value converters and default comparers (
ValueComparer<T>.Default*, various*.Instance) and adjust codegen/baselines to reuse these instead of emitting lambdas. - Update compiled-model scaffolding baselines and tests to remove redundant comparer emissions and to align with the new type-mapping/converter patterns.

RelationalTypeMapping.Clone(...)also removed theclrTypeparameter, which is a breaking change for relational providers/extensions that previously relied onClone(clrType: ...)to retarget a mapping. Consider retaining a compatibility overload (potentially[Obsolete]) which forwards to the new implementation, to avoid breaking external providers on upgrade.

- The base test method was renamed, but some provider test classes still override the old method names, which will cause compilation failures (no suitable method to override). For example:
- test/EFCore.Sqlite.FunctionalTests/Query/PrimitiveCollectionsQuerySqliteTest.cs still overrides
...different_type_mapping() - test/EFCore.Cosmos.FunctionalTests/Query/PrimitiveCollectionsQueryCosmosTest.cs still overrides
...different_type_mapping()
These overrides should be renamed to match the new ...different_property() methods (both the Count and Contains variants).

- RelationalTypeMapping.Clone is a public API, and removing the
clrTypeparameter is a breaking change for providers/extensions that relied on changing the model CLR type without introducing a converter. This also appears to force test-only workarounds (e.g. adding a dummy converter just to carry a different CLR type). Consider preserving this capability via an alternative API (or otherwise providing a supported migration path) while still enabling the NativeAOT-friendly generic type-mapping path.
