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

…last part. (#107615)

(this is the part related to bolt, lld and mlir)

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.
