Return false when queried on secure decoder support pre JB MR2

Although this won't cause any crash currently, but we'd better return false so MediaCodecBridge will not be misused.

Rename fileBrowserPrivate.logoutUser to logoutUserForReauthentication.

The method is used for navigating the user to the GAIA login
screen (which we can only during the account log-in flow for now on
Chrome OS), when for some reason Files.app detected token invalidation.

This CL renames the private API to clarify its purpose.
In later CLs, I'd like to ensure that the API does navigate
the user to the the desired login flow, for fixing 307642.

Minor fixes to GYP generation for GN.

Add an is_gyp flag (currently not set anywhere, will be set when gyp_chromium invokes us) for build scripts to know when we're in GYP generation mode.
