feat: add calling chrome devtools endpoint for chromium

[KazuCocoa]

Chrome browser support /session/:sessionId/goog/cdp/execute endpoint.
Selenium bindings, afaik Java, Python and Ruby, have the endpoint.

We also can support it for chromebrowser. Below is an example.

> @driver.execute_cdp 'Page.getResourceTree'
=> {"frameTree"=>
  {"frame"=>{"id"=>"39B491DE0055515F0F352E11054854F9", "loaderId"=>"3E11DD1F2E9E020331C94E2E02E608E7", "mimeType"=>"text/plain", "securityOrigin"=>"://", "url"=>"data:,"},
   "resources"=>[{"contentSize"=>0, "mimeType"=>"text/plain", "type"=>"Document", "url"=>"data:,"}]}}

https://chromedevtools.github.io/devtools-protocol

Without this change, Appium returns below error.

and the command name

[KazuCocoa]

yeah, I was modifying

[mykola-mokhnach]

goog is a vendor prefix in such case. It makes sense to replace it with a pattern matcher, like :vendor

Good 👍 like it.
