replace library type strings with an enum

This patch creates an enum for selecting libtype as static, shared,
prefer-static, or prefer-shared. This also renames 'static-shared'
with 'prefer_static' and 'shared-static' with 'prefer_shared'. This is
just a refactor with no behavioral changes or user facing changes.
