Introduce new string table optimized for JVM class files

Browse Source 
This format of the string table allows to reduce the size of the Kotlin
metadata in JVM class files by reusing constants already present in the
constant pool. Currently the string table produced by JvmStringTable is not
fully optimized in serialization (in particular, the 'substring' operation
which will be used to extract type names out of generic signature, is not used
at all), but the format and its complete support in the deserialization
(JvmNameResolver) allows future improvement without changing the binary version
