Consolidate profile facilities and improve caching efficiency

Is your feature request related to a problem? Please describe.

Potentially related: #2577 #3303

Describe the solution you'd like

We should reduce the amount of times we read from disk when using the ProfilesCache facility. We also should cache more information in the profiles cache, or at least cache both the ProfilesCache and ProfileInfo instances, re-using them wherever possible.

Describe alternatives you've considered

We can continue to use the facilities available in the codebase, but the issue of excessive profile I/O operations and the scattered function implementations will continue to fester until it becomes a primary bottleneck in some Zowe Explorer actions/operations.
