Enable ClangTidy check modernize-make-unique.

The majority of existing call sites were automatically updated using
clang-tidy -fix. A small handful required a manual update,
e.g. CppCodeGen.

This check is a bit lenient, and in particular will not flag cases like
`std::unique_ptr<Base>(new Derived())` which is still pretty common
throughout our codebase. This CL does not attempt to replace all the
cases that ClangTidy does not flag.
