Enhancement: Identifier repository search

[Capt-Mac]

Problem:

MultiMeasureEvaluationService and CareGapsService both look to utilize resolution of Measure resources by Identifier, but are not able to implement due to a gap in implementation around matching TokenParameters by "SystemUrl" & "Value" or only "SystemUrl" or only "value". Current matching is by Code only.

Resolve by canonical url on multiMeasureEvaluationService is not currently possible and should mirror current pattern of resolving by Id/Canonical/Identifier similar to $care-gaps and r5 specification.

specification: https://www.hl7.org/fhir/R4/search.html#token
https://hl7.org/fhir/R5/measure-operation-evaluate-measure.html

Solution:

Amend TokenParameter searches to account for the missing scenarios so we can implement parameters to resolveByIdentifier into clinical reasoning operations.

Add resolve by canonical url to multiMeasureEvaluationService to mirror $care-gaps operation parameters
