Refactor FHIR resource loading and update tests

Updated `LibraryRunner.cs` to add a comment about re-adding FHIR resource loading functionality and introduced a `libraryIdentifier` variable.

In `MeasuresTest.cs`, removed the import for `Hl7.Cql.Fhir.Serialization.Extensions` and modified the `BCSEHEDIS2022_Numerator_FromResource_Passed` test method to use `InvocationToolkit` for creating runtime scopes. The method `CreateRuntimeScopeFromFhirResourceFile` was removed, reflecting a new approach to runtime scope creation in tests.
