Obsolete {FromSql,ExecuteSql}Interpolated

[roji]

Closes #37575

[Copilot]

Pull request overview

This pull request obsoletes the FromSqlInterpolated and ExecuteSqlInterpolated methods in favor of the newer FromSql and ExecuteSql methods. These method pairs are functionally identical (both accept FormattableString), and the PR aims to simplify the API surface by steering users toward the preferred naming convention.

Changes:

• Added [Obsolete] attributes to FromSqlInterpolated, ExecuteSqlInterpolated, and ExecuteSqlInterpolatedAsync methods with clear guidance to use the newer alternatives
• Updated test code throughout the codebase to use the new method names
• Added pragma warnings around tests that specifically verify behavior of the obsolete methods
• Updated code comments that referenced the obsolete method names
