Make inclusion of doc sub-directory optional by adjusting options.

Browse Source 
Allows exclusion of doc and related targets to help when using eigen via add_subdirectory().

Requested by:

https://gitlab.com/libeigen/eigen/-/issues/1842

Also required making EIGEN_TEST_BUILD_DOCUMENTATION a dependent option on EIGEN_BUILD_DOC. This ensures documentation targets are properly defined when EIGEN_TEST_BUILD_DOCUMENTATION is ON.
