[Git][ghc/ghc][wip/fendor/ghci-debugger-unitid] Add `UnitId`` to `EvalBreakpoint`

Hannes Siebenhandl pushed to branch wip/fendor/ghci-debugger-unitid at Glasgow Haskell Compiler / GHC Commits: 31e01836 by fendor at 2025-04-17T14:22:27+02:00 Add `UnitId`` to `EvalBreakpoint` The `EvalBreakpoint` is used to communicate that a breakpoint was encountered during code evaluation. This `EvalBreakpoint` needs to be converted to an `InternalBreakpointId` which stores a `Module` to uniquely find the correct `Module` in the Home Package Table. The `EvalBreakpoint` used to store only a `ModuleName` which is then converted to a `Module` based on the currently active home unit. This is incorrect in the face of multiple home units, the break point could be in an entirely other home unit! To fix this, we additionally store the `UnitId` of the `Module` in `EvalBreakpoint` to later reconstruct the correct `Module` All of the changes are the consequence of extending `EvalBreakpoint` with the additional `UnitId`. -
