This commit implements ddl-start and ddl-end event triggers to identify index creation operations on encrypted tables. Upon creating an index on an encrypted table, the trigger function updates the global state, which can be accessed by the storage manager (mgr) to decide if smgr_create needs to do encryption or not.
The start-ddl function analyzes the CREATE TABLE and CREATE INDEX statements and identifies if the table uses the pg_tde access method. When the table is created or the one on which the index is being created utilizes the pg_tde access method, the start-ddl trigger function populates relevant information about the encrypted table into a global structure. This structure can be accessed using the GetCurrentTdeCreateEvent() function. After the execution of the current DDL command finishes, the end-ddl function clears out this structure.
