Fix IE 200204176 in tarraydef.getmangledparaname for static arrays

Handle anonymous static array types in getmangledparaname instead of
raising an internal error. On subsequent builds, PPU-loaded types may
have typesym=nil when their mangled name is requested, causing the
fallback to getmangledparaname. The previous code only handled
array-of-const and open/dynamic arrays, leaving static arrays to IE.
