Add "%ll" modifier support for tiny printf.

• Tested on ARM32 and ARM64 systems.
• Tested "%lld", "%llu", "%llx" and "%p" format with minimum and maximum ranges. Compared tiny printf output with full printf.

What's the use case for this, how much does it grow the size, and can the code in question be changed to use a different format modifier or be debug() instead? Tiny printf isn't intended to cover all formats but rather still allow some amount of printf on constrained systems. Thanks!
