Add the initial implementation of javy-profiler (#1213)

* Add the initial implementation of javy-profiler

This patch is a follow-up to
#1208.

It marks the initial work to introduce the profiling functionality as
described in #1206.

Concretely, this patch focuses on the Whamm integration:

* Making the necessary changes to the build system to enable building
the profiler library that will be consumed by Whamm.
* Adding a new `profile` command and `profile inject` subcommad to the
CLI
* Gating this functionality under a feature flag.

Structure wise I tried to make this change as self-contained as
possible (see the changes the makefile, and the introduction of the
`profiler` feature flag), allowing for an straightforward removal
from tree if we ever decide that this feture should not stabilized.

* Ignore transitive dependencies when deriving the wasmtime version

This avoid pulling in multiple versions, introduce by transitive
dependencies (e.g., whamm)

* Run build feature assets in CI
