SF: Upgrade to Composer HAL 2.4
Add plumbing for getDisplayCapabilities and getDisplayConnectionType.
The only functional change is that getDisplayType is no longer called
on hotplug.
Bug: 135929065
Bug: 134771872
Test: Rev HAL to 2.4 on crosshatch
Test: libsurfaceflinger_unittest
Change-Id: Ib2c0383397acef9cde860dd64182213ae7cbb286
