[GL Loader] Remove emulation path.

We want to shift the GL loader to load graphics library based on
ro.hardware.egl and ro.board.platform, emulator will switch to set
ro.hardware.egl based on the emulation status. This patch removes the dedicated
graphics driver loading path for emulation.

BUG: 127353494
Test: Build, boot and verify with emulator.
