feat(tools-node): Add a destructureModuleRef function that does all the module reference parsing at the same time

[JasonVMo]

Description

This adds a new helper destructureModuleRef that picks apart a module reference and separates the @scope/name/path parts in the same pass, rather than splitting it up amongst multiple functions. The other functions that use this code are then reworked to call the new function.

Test plan

• passed all the various tests of different paths. Signature is exact including having missing keys for scope/path when not set (instead of returning scope: undefined or path: undefined.
