Don't support quicklz anymore.

We have decided to discontinue support for the QuickLZ compression type.
QuickLZ is no longer maintained and adds unnecessary complexity.
Removing it streamlines the codebase. This is a breaking feature.

This commit removes all QuickLZ-related code, including:
- Configuration options in configure.ac
- QuickLZ extension in gpcontrib/quicklz
- References in documentation and makefiles

Users should migrate to alternative compression methods such as zlib or
zstd, which offers better performance and is actively maintained.
