Sigh. There's really not a good alternative until we decouple
python from lldb better. The only way the build works right now
is by having every executable link against every LLDB library.
This causes implicit transitive link dependencies on the union
of everything that LLDB brings in. Which means that if all we
want is one header file from interpreter, we have to bring in
everything, including everything that everything depends on,
which means python.
There's outstanding efforts to address this, but it's not yet
complete. So until then, this is all we can do.

The existing state of affairs was getting a little unwieldy.
All of LLDB's utility functions and initial configuration was in
the root CMake file. I split this up into 3 separate files and
moved them to relevant subfolders under cmake/modules.
Also, I deleted the add_lldb_definitions() function. It seemed
to be somewhat useless and did not serve any real purpose that
I was able to figure out.

Separate out the necessary component initialization for lldb-server such that the linker can greatly reduce the binary size. With this patch the size of lldb-server on my 64 bit linux release build drops from 46MB to 26MB.

This resubmits r230380. The primary cause of the failure was
actually just a warning, which we can disable at the CMake level
in a followup patch on the LLVM side. The other thing which was
actually an error on the bot should be able to be fixed with
a clean.

An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs. It is like
a regular archive, just without the physical output. To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.
This is *extremely* important on Windows. lldbAPI exports all of the
SB classes using __declspec(dllexport). Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive. The solution to this is for the DLL to link the object files
directly. So lldbAPI must be an OBJECT library.
This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.
As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.

lldb-gdbserver statically links all llvm dependencies. This allows
dead stripping code and reduces total binary size.
This change modifies lldb-plaform to static link llvm dependencies
like lldb-gdbserver.
