rfnoc: Add multi_usrp_rfnoc, modify multi_usrp

This adds a separate version of multi_usrp for RFNoC devices. It is
compatible with RFNoC devices only, and prefers C++ APIs over property
tree usage. The factory of multi_usrp is modified such that it picks the
correct version, users of multi_usrp don't care about this change.

This also introduces some API changes:
- Removing redundant GPIO functions. Now all GPIO control, setting, and
  readback is done with uint32_t's.
- Adding getter/setter for GPIO source. This was done to simplify the
  other GPIO settings, as the source for each pin is not always a
  binary. The CTRL mode, for example, can either be ATR or GPIO.
  However, the source can be controlled by various radios or "PS" or
  some other source.
- Removing the mask from the RFNoC radio controllers' set_gpio_attr().
- Adding state caching to gpio_atr_3000, and a getter for it. Whenever
  an attribute is set, that value is cached, and can now be retreieved.
- Remove low-level register API. Since UHD 3.10, there is no USRP that
  implements that API.
Modifying the filter API in the following ways:
- Splitting filter API getter/setter/list into separate RX and TX
  functions
- Adding channel numbers as an argument
- The filter name will no longer be a property tree path, but rather a
  filter name. For RFNoC devices, this will take the form
  `BLOCK_ID:FILTER_NAME`. For non-RFNoC devices, this will just be the
  filter name (e.g. `HB_1`)
- Removing search mask from listing function. Users can do their own
  searching
