Comma seperated selection of allowed phases for trace (#2963)

Browse Source 
For `-trace_phase` flag, makes the selection of multiple phases possible
by separating them by comma.

**Example Usage:**
```
bazel run //explorer -- <program_location> --trace_file=... -trace_phase=source_program,execution
```
