static_assert typeof log message entries

Please wait to commit this review until all of the code that
causes static_assert failures is committed.

Resolves openbmc/openbmc#2905

Tested: static_assert only

phosphor-logging now static_asserts that each item to be converted
by the printf-like function has integral, enum, floating_point, or
pointer type and each format argument has a type that decays to
a char * type.

Specifically, std::string fails the assertion because
its address would be logged and not the string buffer.  You
probably want your strings to use s.c_str().

Note that we considered automatically applying c_str() to string
objects, but the underlying entry function is constexpr which
makes that impossible.
