Renames LED_BRIGTHNESS_MAX to LED_BRIGHTNESS_MAX in led.h and all
in-tree users of the macro.

led_context.h contains a single struct with max and min period, current
drivers that use it have hardcoded values and they set it at init.
This data is not used anywhere, and it makes very little sense to use
some SRAM for it.
Hardcode the limit for each driver and drop the struct and file.

The API specifies that brightness is 0 to 100, no point checking it in
the individual drivers.

The led_set_brightness API says that brightness is defined as
percentage, add a macro from the max and use it everywhere.

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.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Add support for TI TLC59108 an I2C 8-bit LED driver.
Supported blinkink period: 41ms to 10730ms
Supported brightness value: 0 to 100%
This driver supports the following APIs:
1. led_blink
2. led_set_brightness
3. led_on
4. led_off
This is a modified version of the NXP PCA9633 driver.
