The paths of sysfs nodes are different on multiple build targets and are
also different between the old kernel (5.10) and newer kernel (6.1).
Since usb HAL code is shared by those targets and different kernel
versions, Runtime search the correct paths.

Indicate to the kernel that the usb gadget is pulled up
by writing to `update_sdp_enum_timeout` sysfs node. Write
to this node will inform the kernel that it can lower the SDP
timeout alarm value which is used to detect an SDP port
vs a DCP.
Bug:275687235
Test: Check `update_sdp_enum_timeout` is written into after usb
gadget is pulled up. Verify that the alarm timeout lowers.

UVC is a new USB function supported in Android. This CL adds UVC as a
valid function and gives it a new pid of 0x4ee[de]. UVC function is
guarded by the property `ro.usb.uvc.enabled`. When this property is set
to false, UVC won't be considered as a valid gadget function.
Bug: 242344221
Test: Manually tested that the UVC function is successfully configured
