test: Show the required size when console-record overflows

Browse Source 
When the console-record buffer overflows, show both the current buffer
size and the size needed. This helps the user know what value to set
for CONFIG_CONSOLE_RECORD_OUT_SIZE.

Add a console_out_ovf field to global_data to track the number of bytes
that could not be written due to overflow.
