Add GEOSEARCH / GEOSEARCHSTORE commands (#8094)

Add commands to query geospatial data with bounding box.

Two new commands that replace the existing 4 GEORADIUS* commands.

GEOSEARCH key [FROMMEMBER member] [FROMLOC long lat] [BYRADIUS radius
unit] [BYBOX width height unit] [WITHCORD] [WITHDIST] [WITHASH] [COUNT
count] [ASC|DESC]

GEOSEARCHSTORE dest_key src_key [FROMMEMBER member] [FROMLOC long lat]
[BYRADIUS radius unit] [BYBOX width height unit] [WITHCORD] [WITHDIST]
[WITHASH] [COUNT count] [ASC|DESC] [STOREDIST]

- Add two types of CIRCULAR_TYPE and RECTANGLE_TYPE to achieve different searches
- Judge whether the point is within the rectangle, refer to:
geohashGetDistanceIfInRectangle
