test_common is force-included into every compilation, which causes
problems when we're compiling assembly code, as we were in #138805.
This avoids that as we can include the header only when it's needed.
After 82ba3f4, we (again) need to call lldb_enable_attach to be able to
attach to processes on linux. This was a new test, so it does not have
the necessary boilerplate.
We only had that ability for regular debugger launches. This meant that
it was not possible to use the normal dlopen patterns in attach tests.
This fixes that.
When rebase_exec=true in DidAttach(), all modules are loaded
before the rendezvous breakpoint is set, which means the
LoadInterpreterModule() method is not called and m_interpreter_module
is not initialized.
This causes the very first rendezvous breakpoint hit with
m_initial_modules_added=false to accidentally unload the
module_sp that corresponds to the dynamic loader.
This bug (introduced in D92187) was causing the rendezvous
mechanism to not work in Android 28. The mechanism works
fine on older/newer versions of Android.
Test: Verified rendezvous on Android 28 and 29
Test: Added dlopen test
