Refactor function hypertable_local_size
Reorganize the code and fix minor bug that was not computing the size of FSM, VM and INIT forks of the parent hypertable. Fixed the bug by exposing the `ts_relation_size` function to the SQL level to encapsulate the logic to compute `heap`, `indexes` and `toast` sizes.
