[PATCH] D55702: [clangd] Fix memory leak in ClangdTests.

createInvocationFromCommandLine sets DisableFree to true by default,
which leads memory leak in clangd. The fix is to  use the `BuildCompilationInvocation`
to create CI with the correct options (DisableFree is false).

Fix https://bugs.llvm.org/show_bug.cgi?id=39991.
