Fix TABLE OF %ROWTYPE parameter in package (fixes #200)

On Oracle 18c+, get_element_definition queries ALL_PLSQL_COLL_TYPES
(introduced in 18c) to resolve collection element types. For %ROWTYPE
references, Oracle stores elem_type_name as "TABLE_NAME%ROWTYPE".
The element was incorrectly treated as OBJECT, causing
ensure_tmp_tables_created to embed the type name literally in DDL,
producing ORA-00911.

Detect the %ROWTYPE suffix in elem_type_name, strip it, verify the
table via ALL_OBJECTS, then populate field definitions from table
columns.

On pre-18c databases (e.g. 11g), this code path is not reached
because ALL_ARGUMENTS expands %ROWTYPE into individual fields
at deeper data levels.
