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.

# This makefile aims to make the binaries as small as possible, for us not to
# upload huge binary blobs in the repo.
# The binary should have debug symbols because stack unwinding doesn't work
# correctly using the information in the Minidump only. Also we want to evaluate
# local variables, etc.
# Breakpad compiles as a static library, so statically linking againts it
# makes the binary huge.
# Dynamically linking to it does improve things, but we are still #include-ing
# breakpad headers (which is a lot of source code for which we generate debug
# symbols)
# So, install_breakpad.cpp does the #include-ing and defines a global function
# "InstallBreakpad" that does all the exception handler registration.
# We compile install_breakpad to object file and then link it, alongside the
# static libbreakpad, into a shared library.
# Then the binaries dynamically link to that lib.
# The other optimisation is not using the standard library (hence the _start
# instead of main). We only link dynamically to some standard libraries.
# This way we have a tiny binary (~8K) that has debug symbols and uses breakpad
# to generate a Minidump when the binary crashes/requests such.
