fix: repair E2E test compilation and assertion errors

- Remove duplicate eglVendor constant (redeclared in examples_test.go
  and main.go); use generated egl.EGL_VENDOR/VERSION/EXTENSIONS instead
- Fix DefaultSensor calls to pass sensor.Type directly (not int32 cast)
- Fix ndkcli_test.go assertions to match actual output casing and flags
  (vendor not Vendor, density not Density, --text/--prio not --message/--priority)
- Fix surfacecontrol Visibility enum check (Hide=0, Show=1)
- Make gles3/sync-fences example tolerate FenceSync nil and non-standard
  ClientWaitSync results (GPU driver behavior varies by device)
