[api] Add encode_raw_short_string for forced string fields with max_data_length

Browse Source 
Replace 3-call sequence (write_raw_byte + write_raw_byte + encode_raw)
with single inlined encode_raw_short_string call for forced string
fields with max_data_length < 128. The compiler can hoist the pos
pointer across all three writes in one function boundary.
