Write to /sys/class/typec/port<...>/device/update_sdp_enum_timeout
to reduce SDP enumeration timeout value when device is in charger
mode. This will enable faster detection of a DCP port.
ported from 6710e31a629f81cf308e1099f75a01c82db6d006
Test: Validate (in charger mode) that the sysfs attribute is 1
(meaning lower sdp timeout value is being used). Read dmesg to
see print showing timeout value is 5000ms.

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.

Test: Check `update_sdp_enum_timeout` is written into after usb

The UVC gadget requires some setup in configfs before it can be used by
the gadget HAL. This CL adds that setup to usb specific init.rc file.
Currently, UVC is setup to advertise mjpeg streams at 720p and 1080p.
Bug: 242344221
Test: Manually tested that UVC is correctly set up on boot.

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
