winch: Handle relocations and traps (#6298 )

* winch: Handle relocations and traps

This change introduces handling of traps and relocations in Winch, which
was left out in https://github.com/bytecodealliance/wasmtime/pull/6119.

In order to so, this change moves the `CompiledFunction` struct to the
`wasmtime-cranelift-shared` crate, allowing Cranelift and Winch to
operate on a single, shared representation, following some of the ideas
discussed in https://github.com/bytecodealliance/wasmtime/pull/5944.

Even though Winch doesn't rely on all the fields of `CompiledFunction`,
it eventually will. With the addition of relocations and traps it
started to be more evident that even if we wanted to have different
representations of a compiled function, they would end up being very
similar.

This change also consolidates where the `traps` and `relocations` of the
`CompiledFunction` get created, by introducing a constructor that
operates on a `MachBufferFinalized<Final>`, esentially encapsulating
this process in a single place for both Winch and Cranelift.

* Rework the shared `CompiledFunction`

This commit reworks the shared `CompiledFunction` struct. The compiled
function now contains the essential pieces to derive all the information
to create the final object file and to derive the debug information for
the function.

This commit also decouples the dwarf emission process by introducing
a `metadata` field in the `CompiledFunction` struct, which is used as
the central structure for dwarf emission.
