Pull request overview
This PR addresses issue #51446 by consolidating multiple attribute-related compiler error diagnostics into a single comprehensive article. The changes move individual error documentation pages to a unified "Attribute declaration and usage" article, making it easier to find and understand related errors.
Changes:
- Consolidates 23 attribute-related compiler errors (CS0181, CS0579, CS0592, CS0616, CS0647, CS0668, CS0735, CS0739, CS1608, CS1614, CS1618, CS1667, CS1689, CS8959-CS8963, CS8968, CS8970) into
attribute-usage-errors.md - Adds new section for CallerArgumentExpression attribute errors (CS8959-CS8963) as requested in issue #51446
- Includes generic attribute type errors (CS8968, CS8970) as requested in issue #51446
- Creates redirects for all deleted individual error pages to the consolidated article
