MdeModulePkg: Simplify PrintInternal function to fit wide character
According to UEFI Spec, only Bit0...6 is valid in mode attribute, other
bits are undefined and must be 0. So attribute with EFI_WIDE_ATTRIBUTE
is unacceptable as EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.SetAttribute() input
parameter. In current PrintInternal function, wide character removed
WIDE_CHAR, and is used as EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.OutputString()
input parameter. So, wide character is mistakenly be treated as narrow
character.
Because EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.OutputString() can handle unicode
string with NARROW_CHAR and WIDE_CHAR, we can directly invoke
OutputString() with whole unicode string in PrintInternal function instead
of separated wide/narrow string. And then, the logic of computing unicode
string width is also simplified.

Log Message:
-----------
MdeModulePkg: Improve the implementation of EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL
Fix TestString() to be compatible with wide/narrow string in
GraphicsConsole driver. If WIDE_CHAR or NARROW_CHAR is hit in
TestString function, ignore it since OutputString function will
correctly handle it.
Fix OutputString() to skip wide/narrow char in TerminalDxe. Because
they are not displayable in terminal emulation tool, ingore to
output if they are hit in OutputString function.
