feat!: nargo::ops::test::run_test generic in ForeignCallExecutor

[aakoshh]

Description

Problem*

Follow up for #6857
Fixes the Wasm compilation in #6849

Summary*

Changes nargo::ops::test::run_test to take a generic function to create a ForeignCallExecutor, rather than a URL which it used for now to create a HTTP client, which would not compile to wasm, clashing with the goals of #6835

Refactored nargo to make it possible to import the test features without the rpc stuff. Changed the feature flags to only disable the DefaultForeignCallExecutor for Wasm.

Additional Context

Looks good!

I've been wanting to separate the executor creation from the test runner more so this is great.
