Add Texas Instruments TCA9548A driver scan interactive test

[apcountryman]

Add Texas Instruments TCA9548A driver (::picolibrary::Texas_Instruments::TCA9548A::Driver) scan interactive test (test-interactive-picolibrary-texas_instruments-tca9548a-driver-scan).

• Add the test/interactive/picolibrary/texas_instruments/tca9548a/driver/scan/ directory to the build
• The test should be defined in test/interactive/picolibrary/texas_instruments/tca9548a/driver/scan/main.cc
• The test should perform the following sequence of operations:
  • Configure the clock (::picolibrary::Testing::Interactive::Microchip::megaAVR0::configure_clock())
  • Initialize the interactive testing log (::picolibrary::Testing::Interactive::Microchip::megaAVR0::Log::initialize())
  • Construct a Microchip megaAVR 0-series I2C controller (::picolibrary::Microchip::megaAVR0::I2C::Controller)
  • Run the Texas Instruments TCA9548A driver scan interactive test helper (::picolibrary::Testing::Interactive::Texas_Instruments::TCA9548A::scan())
  • Enter an infinite loop
• The test should have the following build parameters:
  • CONTROLLER_TWI: controller TWI
  • CONTROLLER_TWI_SDA_HOLD_TIME: controller TWI SDA hold time
  • CONTROLLER_TWI_BUS_SPEED: controller TWI bus speed
  • CONTROLLER_TWI_CLOCK_GENERATOR_SCALING_FACTOR: controller TWI clock generator scaling factor
  • CONTROLLER_TWI_INACTIVE_BUS_TIME_OUT: controller TWI inactive bus time-out
  • CONTROLLER_TWI_ROUTE: controller TWI route
  • TCA9548A_ADDRESS: TCA9548A address
• Add ATmega4809 Arduino Nano Every test build configuration (configuration/testing-interactive-atmega4809-arduino-nano-every/test/interactive/picolibrary/texas_instruments/tca9548a/driver/scan/CMakeLists.txt)
  • CONTROLLER_TWI: TWI0
  • CONTROLLER_TWI_SDA_HOLD_TIME: OFF
  • CONTROLLER_TWI_BUS_SPEED: STANDARD
  • CONTROLLER_TWI_CLOCK_GENERATOR_SCALING_FACTOR: 73
  • CONTROLLER_TWI_INACTIVE_BUS_TIME_OUT: DISABLED
  • CONTROLLER_TWI_ROUTE: DEFAULT
• Document the test
  • docs/test-interactive.md
  • docs/test-interactive/picolibrary/texas_instruments/tca9548a/driver/scan.md
