drivers: wifi: esp: support configurable modem ring buffer size

Browse source 
Add new Kconfig option to configure modem UART interface handler ring
buffer size. This will allow to lower ring buffer to save some resources
or increase it in case high network bandwidth is utilized (with high
UART baudrate).
