[Workers] Update worker-size limits docs

[taylorlee]

Summary

• simplify meaning text (avoid wrap, remove XXMB phrasing)
• consolidate remediation recommendations to limits doc (size-err doesn't belong in 10021 section anyhow)
• add 64M uncompressed limit (always existed; never documented)
• mention Assets for hosting static assets
