[lld-macho] Use ld64's LC_LINKER_OPTIONS behavior by default

By default ld64 ignores invalid LC_LINKER_OPTIONS unless the link fails,
in which case it prints a warning. Originally lld chose to be strict
about these, but it has uncovered that many of these exist in open
source projects today, since before developers never would have noticed
this issue. In order to make adoption of lld easier, this mirrors ld64's
behavior, while also adding a `--strict-auto-link-options` flag if
projects want to audit their libraries for these invalid options.
