rts: Improve tracing message when nursery is resized

It is sometimes more useful to know how much bigger or smaller the
nursery got when it is resized.

In particular I am trying to investigate situations where we end up with
fragmentation due to the nursery (#24577)

Don't generate wrappers for `type data` constructors with StrictData

Previously, the logic for checking if a data constructor needs a wrapper or not
would take into account whether the constructor's fields have explicit
strictness (e.g., `data T = MkT !Int`), but the logic would _not_ take into
account whether `StrictData` was enabled. This meant that something like `type
data T = MkT Int` would incorrectly generate a wrapper for `MkT` if
`StrictData` was enabled, leading to the horrible errors seen in #24620. To fix
this, we disable generating wrappers for `type data` constructors altogether.

Fixes #24620.

NCG: Fix a bug where we errounously removed a required jump instruction.

Add a new method to the Instruction class to check if we can eliminate a
jump in favour of fallthrough control flow.

Fixes #24507

EPA: Add additional comments field to AnnsModule

This is used in exact printing to store comments coming after the
`where` keyword but before any comments allocated to imports or decls.

It is used in ghc-exactprint, see
