[bluetooth][win] Force uncached characteristic value reads

The ReadValueAsync() method will return the characteristic value
cached by Windows. It appears that when a value is written to a
characteristic Windows assumes that the device will respond with the
value written and will update its cache to that value. This is a
problem for devices which do not follow this behavior and instead
respond with an unrelated value.

This change switches to using the ReadValueWithCacheModeAsync() method
and passes the BluetoothCacheMode_Uncached flag in order to force
Windows to always read the value directly from the device.
