Summary:
Summary/Context:
- Renamed `cache_rev_mng` to `compression_dict_buffer_cache_res_mgr`
- It is to distinguish with other potential `cache_res_mgr` in `BlockBasedTableBuilder` and to use correct short-hand for the words "reservation", "manager"
- Added `table_options.block_cache == nullptr` in additional to `table_options.no_block_cache == true` to be conditions where we don't create a `CacheReservationManager`
- Theoretically `table_options.no_block_cache == true` is equivalent to `table_options.block_cache == nullptr` by API. But since segment fault will be generated by passing `nullptr` into `CacheReservationManager`'s constructor, it does not hurt to directly verify `table_options.block_cache != nullptr` before passing in
- Renamed `is_cache_full` to `exceeds_global_block_cache_limit`
- It is to hide implementation detail of cache reservation and to emphasize on the concept/design intent of caping memory within global block cache limit
