feat(build): Add CLI version metadata to build upload archives (EME-471)

Adds a `.sentry-cli-metadata.txt` file to all zip archives created during
build uploads. This file contains the sentry-cli version for debugging purposes.

The metadata file is added to both single-file uploads (APK, AAB) and directory
uploads (XCArchive) with the same compression and timestamp settings as other
files to maintain consistent checksums.
