[flutter_plugin_tools] Remove global state from tests (#4018)

Browse Source 
Eliminates the global test filesystem and global test packages directory, in favor of local versions. This guarantees that each test runs with a clean filesystem state, rather than relying on cleanup. It also simplifies understanding the tests, since everything is done via params and return values instead of needing to know about the magic global variables and which methods mutate them.
