Remove Bitmap#createGraphicBufferHandle

Bug: 148155907
Bug: 150395371
Bug: 150956734
Test: make

All internal callers have been moved to getHardwareBuffer. Although the
method was listed as @UnsupportedAppUsage and go/nonsdk-dash-per-api
lists MEDIUM usage, there is no runtime usage logged, and static
analysis only reveals one call site that has been updated.
