ANDROID: Update drm_hwc pre/postsubmit

VtsHalGraphicsComposer3_TargetTest is now passing on post submit on
AVDs, so move it as a presubmit device on both CF and Ika.

Add 2 new tests to postsubmit:
1. CuttlefishDisplayTests tests that the AVD turns on with something on the screen.
2. CuttlefishDisplayHotplugTest tests that the AVD can interactively connect and disconnect displays.

Bug: b/383125262
Test: N/A
Flag: TEST_ONLY
