[goldfish-display] Remove multi-display handling logic.

Change I2116bf1b0681deac84a580f542ad50a4e5629298 removed the
multi-display configuration boot arguments from the goldfish-display
driver.

This change removes all the multi-display handling logic from the
display engine driver. The engine driver now only accepts display
configs with the primary display as the only display device.

Test: "fx shell display-tool squares" on core.x64 (ffx emu)
Test: goldfish-unittests
