Update the semihost_console implementation to use the semihost API
instead of manually constructing the supervisor calls.

Refactors all of the console drivers to use a shared driver class
initialization priority configuration, CONFIG_CONSOLE_INIT_PRIORITY, to
allow configuring console drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEFAULT to preserve
the existing default initialization priority for most drivers.
The driver-specific option, CONFIG_NATIVE_POSIX_CONSOLE_INIT_PRIORITY,
is left intact because the native posix console driver needs to
initialize after the UART console driver when both drivers are enabled.

This also makes it into arch_printk_char_out() which gets linked
in place of the weak symbol version, meaning printk() is usable
as soon as the stack is set up.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Many chips have only one serial port. When the serial port is occupied
by other devices, there is a lack of a console to output debugging
information. Semihosting can provide a console. The disadvantage of
semihosting is that a debugger must be connected, so it can only be
used for online debugging.
