PyPi binary validation and size check (#1230)

* Validate binary size

* Validate binary size linux_job

* evaluate the fix from #1231

* Add an optional artifact upload, consolidate fixes to `prep_binary_for_pypi.sh`

+name: Validate manywheel binaries
+
+# This workflow validates the size of the manywheel binaries after repackaging for PyPi
+# Specify the direct URLs to the binaries (from https://download.pytorch.org/whl/test/torch/) in the matrix
+# along with the python version.
+#
+# The workflow will:
+#  * download the binaries,
+#  * run release/pypi/prep_binary_for_pypi.sh
+#  * run smoke tests on the repackaged binaries
+#  * display the size before and after repackaging as the workflow annotation
+#  * optionally upload the repackaged binaries as artifacts (for debug or promotion)
