Jordan Rupprecht 99451b4453 [lldb][test] Remove symlink for API tests.
Summary: Moves lldbsuite tests to lldb/test/API.

This is a largely mechanical change, moved with the following steps:

```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```

lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.

// LLDB stops in the constructor and then requests
// possible expression completions. This will iterate over the
// declarations in the translation unit.
// The unnamed ParamClass parameter causes that LLDB will add
// an incomplete ParamClass decl to the translation unit which
// the code completion will find. Upon inspecting the ParamClass
// decl to see if it can be used to provide any useful completions,
// Clang will complete it and load all its members.
// This causes that its member function some_func is loaded which in turn
// loads the LoadedByParamClass decl. When LoadedByParamClass
// is created it will be added to the translation unit which
// will invalidate all iterators that currently iterate over
// the translation unit. The iterator we use for code completion
// is now invalidated and LLDB crashes.
