CPU Architecture support (#27924)
* CPU Architecture Support

This commit removes the `native` variant in favor of Spack's built-in support for specifying a target cpu architecture.  It also passes this information to the Legion build system so that it correctly passes the architecture to GASNet when built internally

* fixing whitespace

* Update package.py

based on a conversation with @streichler, this change sets `BUILD_MARCH` to an empty string, which will prevent legion's CMake build system from inserting `-march=native` and allow Spack to provide the correct architecture flags.

* Update package.py

adding a comment on what problem this MR solves.

* Update package.py
