[avro-cpp] Fix static build

[xiaozhuai]

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

Fix #32848

Also fixed these in ci baseline.

IMO the existing usage needs to be rectified (or removed).
It doesn't consistently look for debug and release libs.
It only deals with lib acrocpp. It doesn't carry any link libraries for static linkage. (This doesn't mean that the port wouldn't support static linkage. It just means that users are required to have more knowledge about the package.)
For static linkage, the port could benefit from exporting unofficial cmake config.

@dg0yt
It should work as expected now.

A lot of new comments... Some of the problems are more related to the poor original state of the port/patch, not to the contribution in this PR which is a signifcant progress.

@dg0yt
That's right, I'd like to write a CMakeLists from scratch rather than patch it.

@dg0yt

Now that the patch is smaller and all your suggestions are dealt with, please review again.
