spirv: emit nonsemantic info with zig errors

In order to be able to report nice errors in the test runner, and in order
to check SkipZigTest errors, we need to pass the error names to the consumer.
This kind of information can be passed via nonsemantic instructions - using
OpSourceExtension here.

All errors are concatenated into a single string, starting with 'zig_errors:'
for identification, separated by a colon (:). To ensure that we can represent
all error codes, even those which contain a colon, the error names are URI-
escaped. URI-escaping, rather than base64, allows us to see the error names
when viewing disassembled SPIR-V code.

```
