Remove Parameters library and refactor Driver.

In addition to removing all the extraneous Driver invocations that created various top-level Parameters instances,
this commit also lays the groundwork for stanza-firrtl/verilator based testing of Modules that extend BasicTester.

The execution-based tests have been updated accordingly. They will only succeed if firrtl and verilator binaries have been installed.
Further work is needed on individual tests to use assertions instead of .io.error.
