String backtrace_get_frames(void* const* frames, size_t size, u32 skip_frames = 0)

:params
frames : frame pointer array returned by native backtrace collection
size : number of frames in the array
skip_frames : number of newest frames to omit
return value : formatted backtrace string

:content
Formats a captured native backtrace frame array.

Most page code should use `backtrace_capture()` instead. Use this helper when you already have raw frame pointers from lower-level diagnostic code.

:example
print(backtrace_get_frames(0, 0) == "" ? "(no frames available in the wasm sandbox)" : "frames captured", "\n");
