Peter Bigot 33103828dc lib: add cbprintf capability
This commit adds a C99 stdio value formatter capability where
generated text is emitted through a callback.  This allows generation
of arbitrarily long output without a buffer, functionality that is
core to printk, logging, and other system and application needs.

The formatter supports most C99 specifications, excluding:
* %Lf long double conversion
* wide character output

Kconfig options allow disabling features like floating-point
conversion if they are not necessary.  By default most conversions are
enabled.

The original z_vprintk() implementation is adapted to meet the
interface requirements of cbvprintf, and made available as an opt-in
feature for space-constrained applications that do not need full
formatting support.
