Revert "adding static and dynamic ZigEquivalent

enums so that we can branch to set `link_mode` properly when we iterate
over the clang arguments. also replaced `dynamic` flag in
clang_options_data.zig with proper definition similarly to `static`."

This reverts commit 6af0eeb58d.

This change needs more careful consideration. It regressed
zig-bootstrap due to cmake passing `-static -lkernel32` and zig failing
with error.UnableToStaticLink.
