[libretiny] Inline delayMicroseconds() in hal_libretiny.h

Browse Source 
The wrapper is a one-liner forwarding to Arduino's ::delayMicroseconds.
Add the forward decl to the existing NOLINTBEGIN block (alongside yield,
delay, micros, millis) and inline the body — same pattern as the other
Arduino-flavored wrappers in this header. Drops the out-of-line copy
from components/libretiny/hal.cpp.
