rust/sedona-functions: Improve CRS validation

[paleolimbot]

Several functions, including ST_SetCrs(), ST_SetSRID(), and constructors with an SRID argument like ST_Point()don't currently validate their input. For some of them I added the ability to register them with aCrsEnginesuch that it could be used for validation but this isn't actually used when we register the functions currently. Forthcoming functions likeST_GeomFromEWKT()andST_GeomFromEKWB()` will need this too ( #498 ).

We can either lean in to CrsEngine validation (registered with a kernel) or try to provide something via the ConfigOptions or a thread local. (The ConfigOptions are now available in some places in ScalarUDF execution but we haven't wired them into SedonaDB kernels yet: #248 ).
