samples: drivers: adc: enhance test filtering and config

Make tests and test scenaries depend on the existence of required DT
elements.
Now that samples are filtered automatically depending on DT, remove
platform_allow/exclude from generic test scenarios.
Add more integration platforms to cover most ADC IPs/drivers.
