spi_master: Introduce SPI_MASTER_4BA feature flag
Add a feature flag SPI_MASTER_4BA to `struct spi_master` that advertises programmer-side support for 4-byte addresses in generic commands (and read/write commands if the master uses the default implementations). Set it for all masters that handle commands address-agnostic. Don't prefer native 4BA instructions if the master doesn't support them.
