Sync with SeasideSt/Grease master repo

[jbrichau]

See for changes in 1.16.0: https://github.com/SeasideSt/Grease/releases/tag/v1.16.0

For GemStone, we added the implementation that support temporary file creation to be able to also port the streaming file uploads in Seaside to GemStone

All other changes are about the Smile code style rules which only work in Pharo.

(Recreated this PR in a branch to make the CI action that uses the Slack secret to run)

@dalehenrich Any objections in this PR? The packages affecting GemStone are limited and they are additions.
Would be great to be able to continue developing streaming requests for Seaside in Zinc on GemStone as well ;-)
