When a TerminalType is set to PCANSI, characters in the range 0x00
to 0x1F are control characters. The mapping table for PCANSI maps
TRIANGLE glyphs, ARROW_UP glyph, and ARROW_DOWN glyph into this
control character range and that causes no characters to be
displayed by PCANSI compatible terminal emulators.
The mappings are updated so these glyphs are mapped to ANSI
characters in the range 0x20 to 0x7E.
GEOMETRICSHAPE_UP_TRIANGLE '^'
GEOMETRICSHAPE_RIGHT_TRIANGLE '>'
GEOMETRICSHAPE_DOWN_TRIANGLE 'v'
GEOMETRICSHAPE_LEFT_TRIANGLE '<'

ARROW_DOWN 'v'

The issue is with signed/unsigned comparisons between
Mode->CursorRow and Row and Mode->CursorColumn and Column.
The fix is to add typecast to UINTN for comparisons.

For TtyTerm terminals, output a shorter escape sequence when possible
to move the cursor within the current line, and don't print any escape
sequence if the cursor is already at the correct position. This
removes extra cursor motion activity at the EFI shell prompt,
improving performance. It also makes it possible in many cases to
successfully use a terminal window which is taller than the driver's
mode setting (eg. 80x25.)

When we print the last character on a line, the terminal driver wraps
CursorRow/CursorColumn to the beginning of the next line. But the
terminal itself doesn't wrap its cursor until the next character is
printed. That throws off the driver's cursor position tracking.
So when we have printed the last character on a line, and are not in
the middle of outputing an escape sequence, synchronize the terminal
with the driver by outputing CR+LF. This matches the expected
behavior, and the behavior of the VGA console driver.
Only change the behavior of TtyTerm, not the other terminal types.

This patch a adds new terminal type, TtyTerm, to TerminalDxe. This terminal
type provides a place to add support for various *nix terminals that don't
behave like standard VT terminals. The goal is to 'just work' with as many
terminals as possible, rather than properly emulating any one specific
terminal.

add a judgement of whether the control command is equal with previous one or not.
[Impaction]
Judge if the control command is equaled with previous one. This handler can improve performance.
[Reference Info]
Currently the terminal driver outputs control commands upon user's request regardless of whether the new attribute is the same as previous one or not.
Actually, it could be implemented as only outputting control command when the new Attribute is different than previous one
