Marc Schier 20d9d65a64 Fix generated configuration namespace resolution (#4019)
# Description

Fix source-generated configuration types whose explicit namespace
references constants emitted by the same generator pass. Roslyn cannot
resolve those constants while `[DataType]` attributes are analyzed, so
the generated XML codec silently fell back to `urn:memorybuffer` /
`urn:testdata` while the shipped configuration uses the model namespace
URIs.

This change:

- adds `MODELGEN021` to fail when an explicitly supplied
`[DataType.Namespace]` expression cannot be resolved;
- uses compile-time-available model namespace URIs for the MemoryBuffer
and TestData configuration types;
- restores production-shaped XML fixtures and exercises the
`UpdateExtension<T>()` / `ParseExtension<T>()` path;
- documents the source-generator namespace requirement and migration
guidance.

Targeted validation passed:

- `TypeGeneratorTests`: 17 tests on `net10.0` and `net48`;
- `ConfigurationRoundTripTests`: 4 tests on `net10.0` and `net48`.
