RFR: 8339358: Optimize TypeKind#from

[Shaojin Wen]

TypeKind.from(Class) is a frequently called method, which provides a specialized method to improve performance.

The following Compiler log shows that the call stack level is reduced and two reference accesses (descriptorString() -> String.value) are reduced, which can reduce the performance degradation caused by cache misses.
