Change the "c" variable type from char to uint8_t in get_glyph_ptr() and
draw_char_vtmono() to fix issues with the range check of the "c" value.
The easiest way to print localized text with Zephyr is
to ask GCC for compile-time conversion:

Since the `fb` pointer is always assigned to `char_fb`, there is no need
for a `NULL` check. Additionally, removed setting `fb->buf` to `NULL` in
`cfb_framebuffer_init` as it will be overwritten by subsequent operations.

I broke the rendering of the CFB_FONT_MSB_FIRST font in
the previously committed #53796.
I will correct the entire font rendering process to make it
easier to remove the restriction that the vertical size of
the font must be a multiple of 8.

MISRA Rule 5.7 requires uniqueness of tag identifiers. Shell is
frequently problematic because many code uses `const struct shell
*shell`. This causes CI noise every time one of these shell files is
edited, so let's update all of them with `const struct shell *sh`
instead.

Add the `draw text` command to execute the `cfb_draw_text()` API.
The command is similar to the `print` command. The difference is
`draw text` can render to coordinate that is not on tile boundaries.
The command is not run `cfb_framebuffer_clear()`,
So it allows rendering appendiceal with keeping already drawn image.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.
