The problem is that the when the "attach" command is initiated, the
ExecutionContext for the command has a process - it's the exited one
from the previour run. But the `attach wait` creates a new process for
the attach, and then errors out instead of interrupting when it finds
that its process and the one in the command's ExecutionContext don't
match.
This change checks that if we're returning a target from
GetExecutionContext, we fill the context with it's current process, not
some historical one.
Fix the POSIX-DYLD plugin to update the cached executable path after
attaching. Previously, the path was cached in DYLDRendezvous
constructor and not updated afterwards. This meant that if LLDB was
attaching to a process (e.g. via connecting to lldb-server), the code
stored the empty path before DidAttach() resolved it. The fix updates
the cached path in DidAttach().

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.
