Set Address behavior is not specified when wValue is greater than 127,
or if wIndex or wLength are non-zero. USB stack did check wValue and
wLength but didn't care about wIndex value. Extend the check so non-zero
wIndex also results in STALL response.

Platform capability descriptors such as MSOSv2 or WebUSB BOS have a
vendor request code that is used by the host to perform vendor-specific
requests. Add a convenient way to define and register a platform
capability descriptor with a vendor request node.

Allow the user to register a vendor request node identified by the
vendor code (bRequest) and containing two callbacks to handle the vendor
request. The device stack uses the vendor request node to call the
vendor request callbacks when it receives a request of type Vendor,
recipient Device, and bRequest value equal to the vendor code.

In case the host doesn't pull the new data from the endpoint, the work task
would schedule itself again delayed (at the max. priority). When there is
no terminal program or active application reading the endpoint this
results in a constant polling of the endpoint burning up to 5% of the
CPU cycles.
By using a atomic flag for tx busy, the polling is solved and changed into
a postponed execution of the next work task which saves up to 5% of
CPU cycles and allows a better real-time behavior for other tasks.
Secondly, if the TX interrupt is disabled but there is still data in the TX
FIFO (ring buffer), the implementation will continue to trigger subsequent
TX work and attempt to flush the data to the host.

Verbatim from USB 2.0 specification:
The Remote Wakeup field indicates whether the device is currently enabled
to request remote wakeup. The default mode for devices that support
remote wakeup is disabled. If D1 is reset to zero, the ability of the
device to signal remote wakeup is disabled. If D1 is set to one,
the ability of the device to signal remote wakeup is enabled.
The Remote Wakeup field can be modified by the SetFeature() and
ClearFeature() requests using the DEVICE_REMOTE_WAKEUP feature selector.
This field is reset to zero when the device is reset.
