When a clang tool runs on a translation unit that uses modular headers, no
PPCallbacks will be invoked for the code in the modular headers (since they are
not parsed, but loaded as AST). Since some tools depend on PPCallbacks for all
transitively included headers, a solution is to re-lex the modular headers
from the sources stored along with AST inside module files. This patch makes it
possible to re-attach PPCallbacks from the compiler's Preprocessor to a custom
one that will be used to re-lex all transitively included headers. It also
updates clang-tidy checks to be compatible with this mode of operation.
