Foundation classes - Formatting fixes for deprecated (#851)

- Removed empty lines following `Standard_DEPRECATED` macro declarations to improve code consistency
- Removed `[[nodiscard]]` attributes from deprecated functions in Standard_Real, Standard_ShortReal, and Standard_Integer headers to resolve compiler compatibility issues
- Updated the clang-format-check action's regex pattern to better handle `Standard_DEPRECATED` macro variations
