Increased the size of the error message buffer by 4x, to 511 bytes. (#…

…15728) The previous limit of 127 was causing error messages to get truncated when long identifiers are in use. This will increase the stack usage of any code that is allocating a `upb_Status` on the stack. If we want to support smaller stacks in the future, we could change `upb_Status` to store its capacity inline, so different users can allocate error buffers with different capacity.
