[services] add long long support to printf/scanf

[avtolstoy]

Description

Patches nano variants of _printf_i, _vsfprintf_r, __ssvfscanf_r and _scanf_i to support 64-bit format specifiers.

Also fixes a bug with %X scanf format, which was incorrectly parsing as signed integer (whereas %x worked as intended).

Steps to Test

• wiring/strformat
