fix: Fix the compiler test, and check if it worked. (#6638)

* Add tsick.js to rewrite enums.

tsc generates JavaScript which is incompatible with the Closure Compiler's advanced optimizations.

* Remove unused 'outputCode' variable.

* Rename 'run_X_in_browser.js' to 'webdriver.js'

The Mocha and generator tests can both be run either manually or via our webdriver.  In all cases they run in a browser.  These two 'run_X_in_browser.js' files only apply to webdriver, thus they are confusingly named.

Also delete completely unused (and broken) `run_all_tests.sh`

* Linting improvements to mocha/webdriver.js

Still not at 100%.  Complains about require/module/process/__dirname not being defined in multiple places.

* runTestBlock -> runTestFunction

'Block' means something very different in Blockly.

* Removal of `var` from scripts.

* Add webdriver test to verify compile test worked.

* Resolve conficts with 'develop'.

* Address PR comments.
