[M108 Migration][VD] Add schemes for Tizen TV product

This patch add schemes for Tizen TV product: "mmf", "dvb", "tvkey-apps",
"hbbtv-package", "hbbtv-carousel", "ci".

1. Support mmf scheme for GingaNCL team.

2. DVB scheme is not supported by chromium. Allow EWK API client
   to handle DVB requests via intercept request API.

3. This change adds the "tvkey-apps:" scheme for the Tizen TV products.

4. hbbtv-package://<app_id>.<org_id>/[<path>]

e.g. hbbtv-package://1.F1/index.html

The files for these packages are installed on the TV
filesystem, and the installation of the files is
controlled by the HbbTV engine.

Operator application files are considered a 'secure' location,
so the protocol is passed to the 'RegisterURLSchemeAsSecure' API.

5. The HbbTV 2.0.1 Specification (errata 2) section 6.3.2 adds a new URI
format. This URI format is used for loading hbbtv applications from the
DSMCC carousel. This patch adds the scheme that this format requires to
chromium.

format "hbbtv-carousel://OOOO:CCCC/"
Where OOOO = organisation ID (max 16bit).
      CCCC = carousel ID (max 64bit).

6. Add ci scheme to standard schemes list.
So WebEngine can distinguish it.

Now, the  standard url will convert the host part to lower case.
But the CI address don't need convert it to lower case.

format: ci:// type
eg:     ci://HbbTVEngineProfile1/aux/APPLAUNCH-0020/eurofins_logo_0020.cehtml
