Remove native-image GitHub action from repository

[rgrunber]

Create an entry under GH Releases for built artifacts.

- Triggered only when event is not a "pull_request"
- Create a tag "latest" marked as pre-release and attach latest binary
  artifacts from the source branch
- Use actions/download-artifact no-args to fetch all uploaded artifacts
  into their own folder

(this builds on top of #1159)

Remaining items :

• Package binary checksum data into release
• Binaries should be zipped
• Rename binaries lemminx-${short-sha}-${platform} -> lemminx-${platform}

We can't run this under eclipse/lemminx. It needs to be done under redhat-developer/vscode-xml.

So disable binary uploading and pre-release generation.

Re-located to https:/redhat-developer/vscode-xml/blob/master/.github/workflows/native-image.yaml so this can be merged now.
