♻️ [RUMF-1046] instrument method implementation

[BenoitZugmeyer]

Motivation

Add a new utility function to help instrumenting native APIs and reset the instrumentation.

Changes

• implement the utility function instrumentMethod
• use it in a simple case (locationChangeObservable) to have first look at its usage

Testing
