PR #1715: Generate options.h using CMake only once
Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1715
Using abseil via CMake ExternalProject, for each compilation abseil is reconfigured. This leads to a new options-pinned.h generated and then a new options.h installed. Because of that new options.h file, all projects depending on abseil recompile entirely.
Using file(GENERATE ...) instead of file(WRITE ...) allows generating options-pinned.h only when the content is new or changed.

Merging this change closes #1715
