drivers: gnss: lcx7g: Add Kconfigs for configurable buffers

Browse source 
Added Kconfigs to define the size of:
- UART backend receive buffer
- UART backend transmit buffer
- Satellites array size

and increased the UART RX buffer size a default to 256 as 128
is just on the edge of to small at a baudrate of 115200.
