Delay before injecting events in CtsHardwareTestCases

The delay that we added a while back was removed in ag/13256649. Bring
it back logically in this CL, but only for some devices.

It appears that all affected devices are getting split into multiple
input devices by the kernel, since they have several "application" pages
in their hid descriptors.

We don't have a kernel api to wait for all of these devices to be
started / opened.

To mitigate this, just add back the delay for these devices.

Also, fix line endings in microsoft files.
