Currently, the keyboard size (i.e. number of columns) is static.
This patch allows it to be configured at run time. It's required to
support a keyboard with/without keypad in a single image.
KEYBOARD_COLS_MAX has the build time col size. It's used to allocate
exact spaces for arrays. Actual keyboard scanning is done using
keyboard_cols, which holds a runtime col size.

This patch switches column and row of scancode_set2. That is,
scancode_set2[ROWS][COLS] =
{0x00, 0x01, 0x02, ...,
0x10, 0x11, ...,
0x20, ...,
becomes
scancode_set2[COLS][ROWS] =
{0x00, 0x10, 0x20, ...,
0x01, 0x11, ...,
0x02, ...,
This will allow us to extend the table for a keypad without losing
too much readability.

The current debug message in keyboard_8042.c displays a tuple of
row, column, and press status. Additionally, this CL displays a
keycap label for better readability.
For keycap label mapping table can be adjustable under
"CONFIG_KEYBOARD_SCANCODE_MUTABLE" condition as scancode_set2[] is.
For coral board, Enabling CONFIG_KEYBOARD_DEBUG (w/o this CL)
occupies 652 bytes in flash, and this CL occupies another 312 bytes.

The key codes are now always scan code set 2 so we can create a list of
scan codes and use them easily.

The 8042 scan code set 1 can be directly translated from set 2, with a
256 byte table. With this change, we can always process key stroke in
scan code (set 2), and only translate in the single function
`scancode_bytes`. This is very helpful when we need to do key
processing, for example the buttons_8042 can now be simplified with only
one scan code. And is extremely helpful if we want to do dynamic
translation (i.e., to prevent something like CL:1164725).
For `make BOARD=samus', the free space is also increased from 18472 to
18656 (+184) bytes.
BUG=None
TEST=make buildall; manually installed on Eve and tested by
running 'keyboard' factory test to make sure all key scancodes
are not changed.

Add an option to allow the scancode sets to be mutable. The only
reason to use this is to allow a scancode to be changed at runtime,
for instance to support different keyboards in one image.
The side effect of this is the scancode sets are moved out of the
shared RO section.

This commit adds the 8042 scancodes to the shared objects library saving
504 bytes from the RW image. To enable the space savings, define
CONFIG_SHAREDLIB in the target's board.h file.
