media: Use PlatformVerificationDialog in PermissionContextBase on ChromeOS.

The current infobar/bubble doesn't work well with the text message and help link
for protected media identifier permission request. With this CL, we'll show the
existing platform verification modal UI when using
ProtectedMediaIdentifierPermissionContext on ChromeOS.

When we have an agreement on how to use the current infobar/bubble for protected
media identifier permission request on ChromeOS, we can revert this CL.
