Remove HTML 5 functionality helper code

[titusfortner]

Feature and motivation

This is ApplicationCache, WebStorage, & LocationContext

Usage example

#10344

[titusfortner]

I think what needs to be decided here is how we are handling all of the HTML5 functionality across all the languages.

Next step is essentially an inventory of which of the storage/cache/location things are being supported by JS and which have been removed and decide which direction we want for all of the bindings.

@titusfortner what do we do in the short term? driver.application_cache simply raises and exception right now and will not work in the python side - do we remove it (it's already deprecated) until we come up with the above and possibly implement something else?

[titusfortner]

Next step was to figure out which languages marked as deprecated, which removed and which implemented them in JS.

Then we figure out how they should be done in all of them.

[titusfortner]

More accurately this should be discussing the HTML functionality that was added back in 2015

ApplicationCache, WebStorage, & LocationContext

Need to inventory which languages have methods pointing to outdated endpoints, which ones have re-implemented with JS and which have deleted them.

Per TLC Meeting:

@diemol will list the changes that need to be done in the bindings and then deprecate/remove them
