Propagate breakpoint information when inlining across modules

Tracking ticket: #23394

MR: !10448

* Add constructor `IfaceBreakpoint` to `IfaceTickish`
* Store breakpoint data in interface files
* Store `BreakArray` for the breakpoint's module, not the current module, in BCOs
* Store module name in BCOs instead of `Unique`, since the `Unique` from an `Iface` doesn't match the modules in GHCi's
  state
* Allocate module name in `ModBreaks`, like `BreakArray`
* Lookup breakpoint by module name in GHCi
* Skip creating breakpoint instructions when no `ModBreaks` are available, rather than injecting `ModBreaks` in the
  linker when breakpoints are enabled, and panicking when `ModBreaks` is missing

Remove arity inference in type declarations (#23514)

Arity inference in type declarations was introduced
as a workaround for the lack of @k-binders.

They were added in 4aea0a72040, so I simplified all
of this by simply removing arity inference altogether.

This is part of GHC Proposal #425 "Invisible binders in type
declarations".

Stop configuring unused Ld command in `settings`

GHC has no direct dependence on the linker. Rather, we depend upon the C
compiler for linking and an object-merging program (which is typically
`ld`) for production of GHCi objects and merging of C stubs into final
object files.

Despite this, for historical reasons we still recorded information about
the linker into `settings`. Remove these entries from `settings`,
`hadrian/cfg/system.config`, as well as the `configure` logic
responsible for this information.

Closes #23566.

Pass positional arguments in their positions

By quoting $cmd, the default "bash -i" is a single argument to run, and
no file named "bash -i" actually exists to be run.

rts/Trace: Ensure that debugTrace arguments are used

As debugTrace is a macro we must take care to ensure that
the fact is clear to the compiler lest we see warnings.
