A complete rewrite of the Overview section. The revised text
provides a more logical and comprehensive introduction to the
main concepts and capabilities of Zephyr, without providing
an excessive level of detail. (Those details should be provided
by the remaining sections of the Kernel Primer.)
This rewrite has also resulted in some small changes to the
About Zephyr and other Kernel Primer sections.

This commit enables the use of special toolchains other than
the default. Some architectures have specialized cross-compilers
within the same SDK that need to be enabled for specific platforms
of an architecture.
For example, for Intel MCUs, we have an optimized toolchain that
needs to be used for specific platforms under x86.

Previously, CONFIG_PRINTK being false means none of functions related to
the UART console and serial are compiled into the binary. This
effectively means UART console and serial drivers are disabled.
By decoupling serial drivers from console related configs, additional
options are needed to disable serial drivers and UART console driver
itself. So add those options here to disable UART console and serial,
or else the resulting binaries will be too bloated.

As a side effect, it is now possible to build multiple serial

With this, the UART console has its own initialization which is not
dependent on UART init routines.
This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.
Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.
Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.
Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

This moves the static device definition from the driver file,
drivers/bluetooth/uart.c, into the platform config files for
each platform.
This is another step towards converting UART drivers to
the new driver model. Also, platform config files are a more
logical place for the definition.

... instead of an array index to a global array. This is
an intermediate step to make the drivers conform to
the new driver model.
This only changes from using a direct array index to using
device structs. The UARTs are still staticlly defined.
Later patches will make the drivers utilize the driver
initialization procedure specified by the driver model.

The test was doing some weird dance for computing the time the main task
had slept, context switching between the main task and a helper task.
The tick timestamp that marks the start of the sleep duration, which
should be taken before the main task goes to sleep actually was taken
after it went to sleep, by the helper task. This lead to weird results
sometimes on QEMU, where the main task would report that it had slept
for less time than requested.
Now instead, the main task takes its own tick timestamps, just before it
goes to sleep and right when it awakens.
The helper task takes a timestamp as well, to verify that it did do busy
work while the main task was sleeping. However, some error is allowed
there to compensate for some QEMU weirdness.
