SF: parsing Detailed Timing Descriptor in the framework
The first DTD in an edid is the preferred timing which allows to get
a more precise and more often correct physical size for a display. This
can be used to estimate or correct the dpi in case the edid reports the
wrong size and hwc is not providing the right value.
See edid spec: https://glenwing.github.io/docs/VESA-EEDID-A2.pdf
Flag: com.android.graphics.surfaceflinger.flags.correct_dpi_with_display_size
