Describe the contribution
Clean up the logic associated with building tables. In particular, the real function that sets up the intermediate library and targets is moved to be part of the table tool itself (elf2cfetbl) rather than part of CFE. This way, its implementation can change based on the way the tool works, rather than trying to make everything work like elf2cfetbl does.

Fixes #2483

Testing performed
Build CFE and run tests, ensure table builds work

Expected behavior changes
None

System(s) tested on
Debian

Additional context
Dependent upon corresponding update to elf2cfetbl to add scripts on that side, see nasa/elf2cfetbl#142

CCB - note that the workflow failure reported is this:

Table Tool missing: CFS_TABLETOOL_SCRIPT_DIR must be defined by the tool

This is fixed by nasa/elf2cfetbl#143

Re-reviewed, this should be good to merge, but must be done in the same cycle as the referenced elf2cfetbl PR
