encoding/simplifiedchinese: fix incorrect transform count to avoid infinite loop

If the final character in the source buffer is a single '~' escape
character, size is not updated. The loop either doesn't make progress if
size is zero, or size retains the value from a previous iteration which
may return an incorrect source bytes consumed count.
Count the single '~' as 1 byte consumed.

Fixes golang/go#35118
