hw/bus/spi_hal: Add bus_spi_write_read

This implements new bus driver write_read function for
spi_hal bus driver implementation.

For short transactions (up to 16) bytes, function performs
single SPI transfer that can reduce transaction time by half
or more depending on hal_spi MCU  implementation.
