newlib: Enable C99 format specifier support for newlib-nano
This commit enables the C99 format specifier support for the newlib nano variant since it is required for C99 standard compatibility. Without this, Zephyr applications cannot make use of the format specifiers newly added in the C99 standard such as `%hhu` and `%hhd`. Moreover, the newlib `inttypes.h` defines `PRI*8` macros as `%hh*` even when this configuration is disabled, effectively making the abstraction provided by the `inttypes.h` useless due to lack of universality; for this reason, the C99 format specifier support must always be enabled for both full and nano variants of the newlib. For more details, refer to the issue zephyrproject-rtos/zephyr#45336. Signed-off-by: Stephanos Ioannidis <[email protected]>
