MdeModulePkg/TerminalDxe: Support multiple modes for SetMode function

When the terminal driver is active, currently terminals available through
SetMode function are limited to mode 0 (80x25) despite multiple modes are
configured as MaxMode value (e.g. 3 modes in mTerminalConsoleModeData
list). Improve the function to support multiple modes based on the value.
Additionally add more modes that match with the GraphicsConsoleDxe driver.
This update is expected to help the symptom that the Setup or Shell screen
becomes smaller due to the text mode.
