[maxwell_integration] Get EnvironmentController when creating environment in StartAgent

EnvironmentController is being made a required argument for
CreateNestedEnvironment in fxr/241175. This helps ensure that
Environments aren't abandoned unintenionally and never cleaned up,
especially in tests.

This also refactors AgentLauncher::StartAgent out bin/sessionmgr, since it
is not actually used by sessionmgr currently, and into
tests/maxwell_integration's base test class, MaxwellTestBase.

Test: fx run-test maxwell_integration_tests (although it seems like
StartAgent might be dead code even in this test anyway...)
