rust/sedona-functions: Add SRID argument to ST_Point, ST_GeomFromText, and ST_GeomFromWkb

[paleolimbot]

The "constructor" family of functions accepts SRID arguments in PostGIS; however, our kernels don't support that yet.

We might be able to do this generically with something like

struct SRIDifiedKernel {
  inner: ScalarKernelRef,
}

impl SedonaScalarKernel for SRIDifiedKernel {
   // Wrap the self.inner implementations but ensure we also accept the extra argument
}

We do have ST_SetSRID() as a workaround (where we could perhaps lift or integrate the input SRID handling).
