[NFC] Add explicit #include llvm-config.h where its macros are used, lldb part.

[dfukalov]

(this is lldb part)

Without these explicit includes, removing other headers, who implicitly include llvm-config.h, may have non-trivial side effects. For example, clangd may report even llvm-config.h as "no used" in case it defines a macro, that is explicitly used with #ifdef. It is actually amplified with different build configs which use different set of macros.
