Revert "[CMake] Change lldbAPI to be a CMake OBJECT library."

machines with an error about needing to use string(STRIP_GENEX).

-# 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 file directly.
-# So lldbAPI must be an OBJECT library.
