Add a missing specification of linking against dbghelp
[LLDB] Add a missing specification of linking against dbghelp

The PECOFF object file plugin uses the dbghelp API, but doesn't
specify that it has to be linked in anywhere.

Current MSVC based builds have probably succeeded, as other parts
in LLDB have had a "#pragma comment(lib, "dbghelp.lib")", but there's
currently no such pragma in the PECOFF plugin.

The "#pragma comment(lib, ...)" approach doesn't work in MinGW mode
(unless the compiler is given the -fms-extensions option, and even
then, it's only supported by clang/lld, not by GCC/binutils), thus
add it to be linked via CMake. (The other parts of LLDB that use
dbghelp are within _MSC_VER ifdefs.)
