Delete locs.fpp and update-locs files within fprime

[legounicycler]

F´ Version	3.0.0+
Affected Component	N/A

---

Problem Description

Within fprime, there are a few files sprinked throughout that are not being used anymore. All the files named locs.fpp which contain fpp locations for symbols within each build module are no longer needed since there is now a scan that generates a location index in the build system itself. Similarly, the update-locs scripts next to these locs.fpp files can be deleted.

How to Reproduce

See the files in the config/, Drv/, Fpp/, Fw/, Ref/, and Svc/ directories

Expected Behavior

This isn't a breaking bug, but it is confusing enough that developers who are using Ref as a reference deployment have tried to use these scripts and files and been confused by why they aren't doing anything (see the discussion here: https://github.com/nasa/fprime/discussions/1555)
