Rather than having a second pool implementation only for CDS, use the generic pool implementation. This also uses the abstract resource identifiers to identify CDS blocks, rather than a direct reference.

Is it worth changing comment to "Get CFDS Size from PSP" ?

Should the function have (void) instead of ()?

Describe the contribution
Rather than having a second pool implementation only for CDS, use the generic pool implementation. This also uses the abstract resource identifiers to identify CDS blocks, rather than a direct reference.
Fixes #56
Testing performed
Build and sanity test CFE
Confirm all unit tests working
Also tested/Confirmed that the CFE TBL critical table registry is correctly restored when booting in a processor reset mode. In this case the data is successfully restored from CDS.
Expected behavior changes
No impact to behavior.
System(s) tested on
Ubuntu 20.04
Additional context
This consolidates and simplifies a bunch of code in the CDS access area.
Note that previously there was a separate mutex for the CDS pool and CDS registry. However almost all accesses needed both, because pool access and registry access go together. So this is simplified to one mutex now.
