Ensure to return the right release version

Fow now, if we build Cloudberry from a source zip file (not using git
clone), the version information displayed is not matched the right info,
always return 1.0.0 like this:

```
   PostgreSQL 14.4 (Apache Cloudberry 1.0.0 build dev)
```

In this PR, these changes are made:

- Update the PACKAGE_VERSION string from 1.0.0 to 2.0.0devel, which is
  similar to the way PostgreSQL is using.
- Generate the new configure file with the new configure.ac
- Update the getversion file to take the PACKAGE_VERSION as the base
  version info, and append `+dev.<count>.g<sha>` whenever possible
  unless the current commit is exactly on a tag.

After these changes, will return the right info no matter how they get
the source code, like git-clone, source tarballs.

For each release, we also need to update the version string to match the
right release version manually in each branch.
