Peter Dillinger 4d1ac19e3d aggregated-table-properties with GetMapProperty (#7779) 
Summary:
So that we can more easily get aggregate live table data such
as total filter, index, and data sizes.

Also adds ldb support for getting properties

Also fixed some missing/inaccurate related comments in db.h

For example:

    $ ./ldb --db=testdb get_property rocksdb.aggregated-table-properties
    rocksdb.aggregated-table-properties.data_size: 102871
    rocksdb.aggregated-table-properties.filter_size: 0
    rocksdb.aggregated-table-properties.index_partitions: 0
    rocksdb.aggregated-table-properties.index_size: 2232
    rocksdb.aggregated-table-properties.num_data_blocks: 100
    rocksdb.aggregated-table-properties.num_deletions: 0
    rocksdb.aggregated-table-properties.num_entries: 15000
    rocksdb.aggregated-table-properties.num_merge_operands: 0
    rocksdb.aggregated-table-properties.num_range_deletions: 0
    rocksdb.aggregated-table-properties.raw_key_size: 288890
    rocksdb.aggregated-table-properties.raw_value_size: 198890
    rocksdb.aggregated-table-properties.top_level_index_size: 0
    $ ./ldb --db=testdb get_property rocksdb.aggregated-table-properties-at-level1
    rocksdb.aggregated-table-properties-at-level1.data_size: 80909
    rocksdb.aggregated-table-properties-at-level1.filter_size: 0
    rocksdb.aggregated-table-properties-at-level1.index_partitions: 0
    rocksdb.aggregated-table-properties-at-level1.index_size: 1787
    rocksdb.aggregated-table-properties-at-level1.num_data_blocks: 81
    rocksdb.aggregated-table-properties-at-level1.num_deletions: 0
    rocksdb.aggregated-table-properties-at-level1.num_entries: 12466
    rocksdb.aggregated-table-properties-at-level1.num_merge_operands: 0
    rocksdb.aggregated-table-properties-at-level1.num_range_deletions: 0
    rocksdb.aggregated-table-properties-at-level1.raw_key_size: 238210
    rocksdb.aggregated-table-properties-at-level1.raw_value_size: 163414
    rocksdb.aggregated-table-properties-at-level1.top_level_index_size: 0
