[flutter_tools] remove globals from base/android (#60480)

Remove unnecessary use of globals from base tests, and an android test. This changes the test to avoid bouncing through the global getters, which can lead to incorrectly cached zone values. Switches the memory filesystem implementation to the test implementation
