Revert "TerminalDxe: select the UART's default receive FIFO depth"

This reverts commit 31ae446b1a039a55d0336f2201d77d1032533413.
Changing the receive FIFO depth in Terminal driver Start() is not
recommended.
A new PCD PcdUartDefaultReceiveFifoDepth was added and
MdeModulePkg/SerialDxe driver uses the PCD as the default receive
FIFO depth.
