Replace the inspectable property with an environment variable

The current implementation would enable or disable the inspector
globally when the inspectable property was set on a WebEngineView,
overwriting the value previously set by other pages.

Instead of havind default port for the debugging server and having
to enable debugging on individual pages, use an environment variable,
QTWEBENGINE_REMOTE_DEBUGGING, to enable the debugging server for the
whole application at the same time as specifying the port. The format
is the same as for QTWEBKIT_INSPECTOR_SERVER in QtWebKit.

QTWEBENGINE_REMOTE_DEBUGGING is set by default in quicktestbrowser
to ease development.

This also keeps the input reading from the --remote-debugging-port
command line switch for convenience, but its usage should be
considered internal.

This patch also take the opportunity to remove the unused
DevToolsHttpHandlerDelegateQt::m_browserContext and to move the
ownership from ContentBrowserClientQt to WebEngineContext since
the list of inspectable pages isn't bound to the BrowserContext
anyway.
