NINA libraries for STRIX

Vendored from Arduino (GNU LGPL 2.1 or later, see each library's license file), with these changes so they drive the MKR Vidor 4000's NINA-W102 module through the STRIX FPGA image's pin pass-through instead of Arduino's FPGA peripherals bitstream:

• Arduino_SpiNINA 0.0.2: on the Vidor, uses SAMD21 pins directly (SPI on D8–D10, SS D5, ACK D4, GPIO0 D6, RESETN D7) and no longer calls FPGA.begin().
• ArduinoBLE 2.1.0: the NINA SPI transport (BLE over SPI, NINA firmware 3.0.0 or newer) is also enabled for the Vidor.
• WiFiNINA 2.1.1: unchanged; it uses Arduino_SpiNINA.

The NINA module runs nina-fw 3.0.1, flashed with arduino/strix_nina_passthrough and esptool (see the README).
