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
