David Neto d9ad050a95 spvBinaryParse: fix overruns, handle image format
Add unit tests for all diagnostics issued by spvBinaryParse.

Handle image format operands in the binary parser and the
disassembler.

Document that the callback function pointers can be null,
in which case they are ignored.

Detect exhaustion of input when parsing an operand,
to avoid buffer overruns on some invalid input cases.

Fix the description strings for some operand types.
Make the diagnostic messages for those operand types
consistent between the assembler and binary parser.
