Jim Mussared b2b5bcce28 py/profile: Remove the requirement to disable MICROPY_COMP_CONST.
The only reason that const had to be disabled was to make the test output
match CPython when const was involved.  Instead, this commit fixes the test
to handle the lines where const is used.

Also:
- remove the special handling for MICROPY_PERSISTENT_CODE_SAVE in
  unix/mpconfigport.h, and make this automatic.
- move the check for MICROPY_PERSISTENT_CODE_SAVE to where it's used (like
  we do for other similar checks) and add a comment explaining it.

This work was funded through GitHub Sponsors.
