Issue body
### What needs to get done
1. craft-application should use `<appname>_PARALLEL_BUILD_COUNT`.
2. If it is not set, use `CRAFT_PARALLEL_BUILD_COUNT`
3. If it is not set, take the lesser of `<appname>_MAX_PARALLEL_BUILD_COUNT` and the total number of CPUs on the system.
- If `<appname>_MAX_PARALLEL_BUILD_COUNT` is not set, then use `CRAFT_MAX_PARALLEL_BUILD_COUNT`
4. If neither `MAX` envvars are set and the number of CPUs on the system cannot be determined, do not provide a build count to craft-parts (which will use its default of 1).
### Why it needs to get done
1. To allow setting the number of parallel build jobs
2. To align with the design proposed in https://github.com/snapcore/snapcraft/issues/4537 and https://github.com/canonical/craft-parts/issues/631
