294cc28135 Move inline breakpoint outside of runtime backend 
There was some code smell leaking inline breakpoint implementation into the runtime core backend instead of the compiler itself

a1e8a8f0db fix(runtime-core) Same bug with field-offset as before. 
It will be fixed in a following PR.

0775d496d3 feat(runtime-core) Replace the field-offset crate by a custom offset_of! macro. 
The `field-offset` crate is unmaintained. When using its `offset_of!`
macro on a struct with a field of type `std::ptr::NonNull`, in release
mode, it generates a sigill.

This patch removes the `field-offset` crate, and implements a custom
`offset_of!` macro.

0de7f4fd0b test(runtime-core) offset_of! fails with a struct containing NonNull types. 
It fails only in release mode. That's a bug from the `field-offset`
crate. This patch is a temporary fix.

c4c88f8af5 fix(runtime-core) Remove undefined behavior with mem::transmute. 
In the `wrap` functions, we use `std::mem::transmute(&())` to get the
pointer to the value “around” `wrap` (`Fn` has a method `to_raw` which
declares a `wrap` function, which uses `transmute` to retrieve
`Fn`). This is an undefined behavior. It was working until the
`FuncCtx` is introduced. Since then, the undefined behavior was
causing an error with the Singlepass backend.

This patch stores the pointer to `Fn` in `func_env`, so that the
pointer to the user-defined host function is always predictable.
