Simplify SWIG invocation and handling of generated files.
The `swig_wrapper` target can generate `LLDBWrapPython.cpp` and `lldb.py` in
its own binary directory, so we can get rid of a few global variables and their
logic. `$<TARGET_PROPERTY:swig_wrapper,BINARY_DIR>` can be used to refer to it.
For the moment we still need `LLDB_PYTHON_BINARY_DIR` (global property now) as
a workaround for `set_source_files_properties(), which apparently doesn't work
with generator expressions.
