Add -fbreak-points to control breakpoint insertion

Rather than statically enabling breakpoints only for the interpreter,
this adds a new flag.

Tracking ticket: #23057

MR: !10466

rts: Ensure that pinned allocations respect block size

Previously, it was possible for pinned, aligned allocation requests to
allocate beyond the end of the pinned accumulator block. Specifically,
we failed to account for the padding needed to achieve the requested
alignment in the "large object" check. With large alignment requests,
this can result in the allocator using the capability's pinned object
accumulator block to service a request which is larger than
`PINNED_EMPTY_SIZE`.

To fix this we reorganize `allocatePinned` to consistently account for
the alignment padding in all large object checks. This is a bit subtle
as we must handle the case of a small allocation request filling the
accumulator block, as well as large requests.

Fixes #23400.

Use generated src span for catch-all case of record selector functions

This fixes #23492. The problem was that we used the real source span
of the field declaration for the generated catch-all case in the
selector function, in particular in the generated call to
`recSelError`, which meant it was included in the HIE output. Using
`generatedSrcSpan` instead means that it is not included.

perf tests: Increase default stack size for MultiLayerModules

An unhelpfully small stack size appears to have been the real culprit
behind the metric fluctuations in #19293. Debugging metric decreases
triggered by !10729 helped to finally identify the problem.

Metric Decrease:
    MultiLayerModules
    MultiLayerModulesTH_Make
    T13701
    T14697
