Adds functionality for enabling and disabling DisplayPort Alt Mode
on the port through enableUsbData in the USB HAL to comply with USB
restrictions for heightened security mode.
Test: manual test on device - use enableUsbData dumpsys command to
turn off DisplayPort and then turn it back on while connected to a
partner sink.

Better enforces that only one DisplayPort poll thread should be
active at once. If a new call to setup is made from additional
bind uevents before a disconnect occurs, tells the old thread
to shutdown and awaits signaling before a new worker thread spins
up.

When booting check whether displayport driver has been probed and
signal hpd events as needed. Pin config and orientation needs to
be queried before signalling hpd.

The change exposes persist.vendor.usb.displayport.enabled
to enable/disable USB-C Dp Alt Mode i.e. DisplayPort over USB-C.
By default persist.vendor.usb.displayport.enabled is to 0 in
user builds and 1 in all other build variants.
