[roll] Roll fuchsia [usb-peripheral] Cancel only allocated endpoints

In CompleteFunctionsTeardown(), UsbDciCancelAll() previously swept
across all 32 possible endpoint addresses (0x00-0x0F OUT and 0x80-0x8F
IN) to ensure active hardware DMA requests were canceled.

On controller drivers such as dwc3, calling CancelAll on an unallocated
endpoint returns ZX_ERR_INVALID_ARGS because no user endpoint struct
exists. Rather than suppressing ZX_ERR_INVALID_ARGS in
UsbDciCancelAll(), query endpoint_map_ before clearing it and only
cancel endpoints that were actually allocated to functions (EP0 is reset
during StopController()). This eliminates the spurious teardown errors
while keeping strict error logging intact in UsbDciCancelAll().

Additionally, in CommonControl(), validate that non-control endpoints
are allocated in endpoint_map_ before executing SET_FEATURE,
CLEAR_FEATURE, or GET_STATUS, preventing spurious errors if a host
issues control requests for unallocated endpoints.

In usb-peripheral-unittest:
- Record cancelled endpoints in FakeDevice and provide test inspection.
- Add ClearFunctionsCancelsOnlyAllocatedEndpoints verifying that
  ClearFunctions() cancels only allocated function endpoints.
- Verify SET_FEATURE(ENDPOINT_HALT) rejects unallocated endpoints.
