Remove unused ignore parameter of extends() directive (spack#35588)

The `ignore` parameter was only used for `spack activate/deactivate`, and it isn't used
by Spack Environments which have their own handling of file conflicts. We should remove it.

Everything that handles `ignore=` was removed in spack#29317 and included in 0.19, when we
removed `spack activate` and `spack deactivate` in favor of environments.  So all of these
usages removed here were already being ignored by Spack.
