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
BenchmarkParseJWTStandardClaims-32    	 5634847	       214.7 ns/op	     544 B/op	       9 allocs/op

BenchmarkParseJWTMapClaims-32    	 2763045	       428.6 ns/op	    1251 B/op	      29 allocs/op
BenchmarkParseJWTMapClaims-32    	 2839455	       410.9 ns/op	    1219 B/op	      26 allocs/op
