Add CPack to CMakeLists.txt for binary and source package generation (#4645)

Add CPack to CMakeLists.txt.

All default package exports are enabled for tiledb project so the superbuild's `package` command generates outputs based on the current platform (TGZ for Linux).

Usage:

- *Superbuild*
  - `make package` invokes `cpack` inside of the EP tiledb.
- *Build*
- `cpack` for default behaviour or `cpack -G <GENERATOR>` for specific
output
  - `make package`
  - `make package_source`

Example output from Superbuild's `make package`:
```
TGZ
CPack: Create package using TGZ
CPack: Install projects
CPack: - Run preinstall target for: TileDB
CPack: - Install project: TileDB []
CPack: Create package
CPack: - package: /mnt/c/Users/dbara/CLionProjects/TileDB/build_superbuild/tiledb/tiledb-linux-x86_64-2.20.0.tar.gz generated.
CPack: - checksum file: /mnt/c/Users/dbara/CLionProjects/TileDB/build_superbuild/tiledb/tiledb-linux-x86_64-2.20.0.tar.gz.sha1 generated.
```
