### What changes were proposed in this pull request?
Introduce the catalyst-internal geospatial in-memory layout for Geometry and
Geography: `SRID` (integer value) header + `WKB` (byte array) payload, and add
core conversion API to retrieve these values from the server-side execution
wrappers.
### Why are the changes needed?
Establish a consistent representation/encoding for geospatial types, with a
clear contract towards `Geometry` and `Geography` classes. This also provides
minimal safe SRID & WKB extraction in execution and lays the groundwork for
standard format support, conversions, etc.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Added the appropriate unit tests to validate SRID and WKB extraction from
the in-memory data formats:
- `GeographyExecutionSuite`
- `GeometryExecutionSuite`
### Was this patch authored or co-authored using generative AI tooling?
No.
