feat(cli): parallel sdk testing (#3723)

Fixes the 5th and 6th points in #2689
Fixes: #3527
Fixes: #3224
## Description:
* Stop copying wing files when testing on cloud targets, instead changed the target dir to a random tmp dir.
* Separating env vars to be present in compilation context only (those are present only on the compiled artifact, not in its imports, so vars like WING_TARGET and WING_IS_TEST are still out). 
* Moving WING_SOURCE_DIR env var to the app constructor- this way it can be passed in the code easily and doesn't depend on global env.
* Upon testing, adding an extra nanoid to the tf and cdk root resource name, to prevent having resources with the same id over the different tests
* Fixing `Bucket.tryGet`, `Bucket.tryGetJson`, `Bucket.tryDelete` since were failing on aws targets
* adjusting the tests
* generating snapshots

**All code changes can be found on the 1st commit (16 FILES), 2nd one is for snapshots (290~ FILES)**
