GlueGen Struct [8]: Revised setter (resolved shrinking array, using 'subset' flag), added (detailed) JavaDoc in generated code

Revised setter:

A) int32_t val[10] -> setter for a subset change only, as-is with args[src, srcPos, destPos, length]
                     - no new memory, reuse only
                     - no special action to be performed

B) int32_t* val -> setter with toggle 'subset' with args[subset, src, srcPos, destPos, length],
                - replace memory w/ 'subset==false' where it also may copy 'destPos' gap from old -> new
                - reuse memory w/ 'subset==true', where destPos+length <= elementCount

C) const int32_t* val -> setter to replace referenced memory only args[src, srcPos, length]
                     - always replaces memory, no copy of a gap (no destPos)

Hence:
- case (A) stays as is
- case (B) will be revised and argument 'boolean subset' added
- case (C) will be revised (simplified) and argument 'destPos' removed
