Subject: [PATCH 1/2] Add option `MSGPACK_BUILD_DOCS`.

This option explicitly controls the generation of targets related to
Doxygen generation, rather than relying solely on whether Doxygen is
discovered.

It is enabled by default to preserve existing behavior, but if disabled
then no Doxygen targets will be generated. This is useful when the
library is included via CMake's `add_subdirectory()`.
