Follow-up to the 4-bit keyboard BMP conversion in PR #969 for the
remaining two icon assets in VirtualKeyboardDxe.
SimpleIcon.bmp uses only 2 unique colors (pure black/white);
convert to 1-bit paletted BMP for a byte-level lossless reduction.
FullIcon.bmp uses 198 unique colors; convert to 8-bit paletted BMP
for a byte-level lossless reduction (198 < 256 palette entries,
no quantization required).
EDK2 BaseBmpSupportLib already supports 1-bit and 8-bit uncompressed
BMP (TranslateBmpToGopBlt handles both BitsPerPixel values).
Per-file size reduction (24-bit -> target):
SimpleIcon.bmp: 2814 -> 182 (1-bit)
FullIcon.bmp: 5454 -> 2878 (8-bit)
Pixel dimensions and visual layout are unchanged.

Convert the three VirtualKeyboardDxe keyboard bitmap assets from
24-bit BMP to 4-bit paletted BMP. Each bitmap uses fewer than 16
unique colors after median-cut quantization, so the 16-color palette
is sufficient. Pixel dimensions and visual layout are unchanged.
EDK2 BaseBmpSupportLib already supports 4-bit uncompressed BMP
(TranslateBmpToGopBlt handles BitsPerPixel==4).
Per-file size reduction (24-bit -> 4-bit):
CapitalLetterKeyboard.bmp: 330454 -> 55318
DigitKeyboard.bmp: 330454 -> 55318
SimpleKeyboard.bmp: 30054 -> 5318

The Keyboard.c driver did not include ScanCodes like F1,F2,F12,etc.
and UnicodeChars like Backspace, Tab in VK_NOTIFY NotifyList
which is why these keys were not getting registered and
not getting pushed in the KeyBuffer stack which resulted
in undefined behavior of continuous backspace and not recognizing the
relevant key push after the buffer overflow condition.

slow with I2C touch panel
On one Touch, multiple Reads happend and this reads varying based on Key Press time.
Resulting in Multiple key press update on screen. This condition avoids KeyPressed skips
resulting due to faster key press and update only on valid key press.
