In the kernel, it is possible for the DisplayPort Alt Mode
driver to queue an Enter Mode message to the tcpm and have
that message be interupted by a Power Role or Vconn swap,
which results in the Port Partner never entering Alt Mode.
Add a debounce that checks to make sure that the port partner
enters Alt Mode when DisplayPort Alt Mode is active on the
port. On trigger, reattempt to send Enter Mode through the
tcpm up to 2 times.
Test: Manual test on device - put device into Preferred
Source role, test to see if Alt Mode reentry triggers
when original entry is interrupted by PR Swap from
monitor.

Report COMPLIANCE_WARNING_INPUT_POWER_LIMITED instead of
COMPLIANCE_WARNING_OTHER to flag incompatible chargers. The underlying
logic that generates the warning remains the same, what's changed is
the enum that's being used.
The purpose of the change is to have a warning type that better
represents what actually happens and free up COMPLIANCE_WARNING_OTHER
that was intended to act as a fallback reason code.
The flag enable_input_power_limited_warning controls whether to switch
to the new enum, while the flag enable_usb_data_compliance_warning
controls the new enums that are added as FlaggedApi in the framework.
Both flags need to be on to enable the change.

Test: manual tests with local flag override

Query the port partner's SVIDs when the DisplayPort driver sysfs
is not recognized so that the USB HAL can identify whether or not
the port partner supports Thunderbolt.
Test: manual verification on device - test to see that cableStatus
is set to NOT_CAPABLE on hub that supports Thunderbolt but not
DisplayPort Alt Mode. Then verify that device not capable of being
a DisplayPort sink but does support Thunderbolt does not trigger
this status.

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.

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.

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.

Poll the sysfs attributes that represents usb device state in
either of the following states: not attached, powered, default,
addressed, configured.
The information is useful in detecting non compliant USB cable,
which will be supported in later patch sets. This patch lays
the ground work to monitor the sysfs attributes in both device
and host modes.
The thread to poll uevent is re-used to poll sysfs because this
serialize type-C port events and usb device state changes, hence
prevent potential races.
Added a thin abstration layer and a map to keep epoll data so
that it's easier to dynamically add/delete files to epoll, which
is needed for usb devices in host mode.
