Use uint16_t variables for i2c slave_rx_buffer_size and slave_rx_count
variables. This allows to receive more than 255 bytes in slave mode. The
bytes are received one by one in slave mode so there are no hardware
limitations forcing a 1 byte rx count limit.
Summary of changes
Allow I2CSlave::read method to operate on more than 255 bytes for STM32 H7 MCUs.
