jwt: Parse standard claims faster (#13821)

* Use structless/allocationless decoding for header (note "typ" isn't used)
* Create custom unmarshal code using jsonparser for StandardClaims.

Before/After:

```
BenchmarkParseJWTStandardClaims-32    	 4270724	       294.0 ns/op	     706 B/op	      16 allocs/op
