Refine memory allocation in ICU conversions
The simple calculations done to estimate the size of the output buffers
for ucnv_fromUChars() and ucnv_toUChars() could overflow int32_t for
large strings. To avoid that, go the long way and run the function
first without an output buffer to get the correct output buffer size
requirement.
