```
std.debug: allow fp unwind from context

It's easy to do FP unwinding from a CPU context: you just report the
captured ip/pc value first, and then unwind from the captured fp value.
All this really needed was a couple of new functions on the
`std.debug.cpu_context` implementations so that we don't need to rely on
`std.debug.Dwarf` to access the captured registers.

Resolves: #25576
