This PR adds tests for #2219 by changing the `compilation_on_android_ubuntu.yml` workflow.
The first run will take about two hours, since LLDB is built from scratch. Later, the build is
cached and the whole job should not take more than three minutes.
Core of the PR is an integration test that boots up vscode and lets it debug a test WASM file.
This should allow users to use the vscode extension on ubuntu 20.04.
After https://github.com/bytecodealliance/wasm-micro-runtime/pull/2132 ,
our lldb binary for 20.04 works on ubuntu 22.04 as well.
On the other hand, lldb for 22.04 has no chance to work on ubuntu 20.04.
(because of glibc version requirement.)
Download and install the WAMR patched LLDB binary on vscode extension activation.
This allows the user to download the packaged .vsix file, where the activation script
should handle determining what LLDB binary they should use, and install it in the
correct location.
