Fix clobbering of process vs component vs forc

[alfiedotwtf]

These issues were found while investigating #654.

Currently, component_name was being repurposed for multiple functions:

• Checking whether or not the executable was published by forc
• Checking whether or not the executable was in the store
• Used to generate the tarball target
• Used to generate the tarball URL
• Used to generate the final target executable to run from the store

Each of the above was breaking in subtle ways depending on which executable was being run.

After separating out these functions based on the properly resolved component from the executable, and along with the previous commits, these problems above were resolved.

Can we add some tests to show how this change works?

Keeping this PR in DRAFT but backgrounding for now...

90% of the tests have been done, I just have to do the other 90%. Backgrounding for now, but will leave this as a downtime task to complete.
