lib/igt_kms: Add support for detecting connector events

Currently, the event_detect function checks the property val for
"HOTPLUG" and "LEASE" both of which are set to '1' when these events
are sent.

This cannot be used for detecting connector events such as HDCP event
as connector events are sent along with property to signify which
property of which connector has changed. Connector ID and property id
are provided along with "CONNECTOR" and "PROPERTY" as udev
property-value pairs. Eg. for HDCP, the connector id of the connector
whose hdcp status changed, and the property id of the
‘CONTENT_PROTECTION’ property are sent with uevent.

This patch modifies the event_detect function to check multiple
properties with different expected values. It also adds support to
detect connector event for a given pair of connector and property ids.

v2: Simplified the event_detect conditional statements. (Ram)
    Changed the api name for detecting connnector events. (Anshuman)
    Added check for "HOTPLUG" property value for connector events.
v3: Used ARRAY_SIZE() instead of constants. (Ram)
v4: Rebase
