This change addresses several issues with ts-api-guardian and public api guards related tests in Windows
The fixes contain 3 main changes:
1) In `stripExportPattern` - replace `^` with `^^^^` in RegExp due to a double escaping requirment under Windows. Note that under Linux this the extra character has no effect because it's still a valid RegExp in Js.
2. Force `*.patch` files to always be with a LF line sequence instead of CRLF in windows
3. When adding JSDoc comments consider the presence of a carriage return in a line new feed
