Move libsfplugin to libui for graphic mapper

Instead of supporting mapper4 and mapper5 directly, we can use
GraphicBufferMapper which handles the backwards compatibility for us.

This should be the same exact behavior for the HIDL graphics mapper4
with the added support for the mapper5 HAL.

Test: atest mc_sanity_test ccodec_unit_test (same as b/156167471)
