Enhancement request to allow configuring CPU and memory for Multipass instances in craft-providers. Open for 2.5 years with no implementation or assignee.

Suggested action: keep open

Reason: The issue is a clearly scoped enhancement request (labeled 'Type: Enhancement') that correctly identifies hardcoded defaults in `craft_providers/multipass/_launch.py`. It should remain open in the backlog for future implementation, though it requires prioritization given its age.

Issue body

### What needs to get done Provide a way for applications to define the CPU and memory for a Multipass instance. The number of CPUs could be set by craft-application based on `CRAFT_MAX_BUILD_COUNT` and `CRAFT_MAX_PARALLEL_BUILD_COUNT`. Alternatively, a user could define it with something like `snap set snapcraft provider.cpus = <num cpus>` and craft-application would pass this value to craft-providers. I'm not sure how this will get passed to craft-providers, but it will probably be similar to how https://github.com/canonical/craft-providers/issues/191 will pass data about `mknod` needing to be enabled. Source: https://github.com/canonical/craft-providers/issues/212 ### Why it needs to get done Craft-providers [hardcodes](https://github.com/canonical/craft-providers/blob/35bd3c49f3860a74f7f1f424873908581654d968/craft_providers/multipass/multipass_provider.py#L109) Multipass instances to 2 CPU cores and 2GB memory. This make builds slow (or impossible).
