stacktrace: Enable method signature printing for inlined frames (#53925)

This is an attempt to revive #41099 using the newly added invert
linetable format (#52415).
It's a work in progress, but I've opened this PR to spark a discussion
on whether I'm moving in the right direction with this approach.
Currently, I've tweaked `jl_lookup_code_address` to give back a
`CodeInstance` containing `debuginfo` rather than the `MethodInstance`
for the outermost frame. This info is then used to find the
`MethodInstance` for inlined inner frames from the Julia side.

```julia
julia> function f1(a)
           x = a
           return begin
               @inline f2(x)
           end
       end;

julia> function f2(a)
           x = a
           return @inline sin(x)
       end;

julia> f1(Inf)
ERROR: DomainError with Inf:
sin(x) is only defined for finite x.
