Use tester (disclaimer, written by me) to unit test the flutter tools general shard. Since these tests are designed to be hermetic, the single compilation/single isolate model offers a tremendous speedup over the default pub run test workflow. On previous linux shard, test execution alone took 10:30, while now it takes only 1:30.

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

This makes `pub get` in the macrobenchmarks folder.

The global packages path could cause tests to fail when it would be overriden to unexpected (in test setup) values. Remove most usage and make it a configuration on buildInfo, along with most other build information. Cleanup the asset builder to require the .packages path and the resident runners to no longer require it, since they already have the information in build_info.
It needs to stick around for the fuchsia deps we do not control.
Filled #60232 for remaining work.
