RFR: 8263992: Remove dead code NativeLookup::base_library_lookup [v2]

[Ioi Lam]

> Please review this removal of dead code, and unused parameter of `in_base_library` for the functions that remain. The word `base_library_lookup` does not exist in any C source code in the entire JDK.

Ioi Lam has updated the pull request incrementally with one additional commit since the last revision:

  removed unused "in_base_library" parameter; removed unnecessary include of nativeLookup.hpp
