>> A peek into TypeKind during the research for #19105 reveals that TypeKind has a few issues:

>> 2. `fromDescriptor` can throw IOOBE if the input string is empty: changed to throw IAE and added tests.
>> 3. `from(Class)` can be slow due to descriptor computation: added benchmark, will share result in next comment (as it may change with code changes).
