Currently, the buffer of 128KB is passed to GetConsoleProcessList().
This causes page fault in the select() loop for console due to:
https://github.com/microsoft/terminal/issues/18264
because the previous code calls GetConsoleProcessList() with large
buffer and PeekConsoleInput() with small buffer alternately.
With this patch, the minimum buffer size is used that is determined
by GetConsoleProcessList() with small buffer passed.
