`System.Transactions.Locals.Tests` Fixes https://github.com/dotnet/runtime/issues/50969
`System.Threading.Tasks.Parallel.Tests` Fixes https://github.com/dotnet/runtime/issues/51677

* [wasm][aot][tests] Enable `System.Xml.Xsl.XslCompiledTransformApi.Tests`

The individual test failures are already disabled with
https://github.com/dotnet/runtime/issues/51244, and
https://github.com/dotnet/runtime/issues/51911 .
