testsuite: Fix normalisation of prof_files removing newlines

These normalisation steps were collapsing lines together, which made
subsequent normalisation steps fail.

```
foo x y z
CAF x y z
qux x y z
```

was getting normalised to

```
foo x y z qux x y z
```

which means that subsequent line based filters would not work correctly.

packaging: Enable late-ccs for release flavour

This enables late cost centres when building profiled libraries and
subsequently greatly improves the resolution of cost centre stacks when
profiling.

This patch also introduces the `grep_prof` test modifier which is used
to apply a further filter to the .prof file before they are compared.

Fixes #21732
