0ffcc07a81 [linux_input_sys/data_model]: signed input_event
Previously we restricted the virtio_input_event/input_event's value
field to u32. In actuality, this field is an i32 in the kernel, and the
negative values are used for relative mice (among other things). This CL
switches the value field to be signed.

BUG=None
TEST=builds (also tested on another branch)

dc7f52bdb7 Use simple virtio_input_events where possible.
Previously, all input events in CrosVM were required to be linux
input_events, which have a timestamp field that is actually unused by
when we send/receive from the guest which are of type
virtio_input_event. This CL allows CrosVM to understand both types of input
events in a first class manner. It is a follow up on
https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1930405.

This CL also addresses some bugs with window driven input:
1. attach_event_device was being called before the surface was
created, so the devices were never attached.
2. The default touchpad size was not being set to the display window
size.

Additionally, it removes the unused event "filter" feature on event
sources.

Breaking change: from this point forward, CrosVM will treat input events sent
via a socket (e.g. SocketEventSource) to be virtio_input_events.
