misc: Remove Firefox marionette-client in favor of Geckodriver

[AtofStryker]

What would you like?

I would like to remove references to the forked marionnete-client and replace it with a modern alternative like Geckodriver

Why is this needed?

the originally forked/copied marionette client is no longer supported by the Mozilla team (see bugzilla issue). The recommended approach is to replace the Webdriver Classic and extension methods (to add the Cypress web extension) with Geckodriver). This is a prerequisite to Webdriver BiDi support

Other

Geckodriver will be used by Firefox with or without BiDi support as we need it to create the WebDriver Session. Cypress needs to release this change first to make sure there are no regressions with the switch from marionette to geckodriver
