By performing output to presym files after header files, there is no longer a need to check for the existence of header files.
Furthermore, concentrating the file output logic into an "if" block eliminates the need for the `update` variable.
Strict atomicity between presym files and header files is still not guaranteed, as before.
If atomicity is truly required, it can be achieved by deleting the presym file before updating the header files.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the presym file generation process within the Rake tasks. The primary goal is to simplify the code by removing unnecessary conditional checks and consolidating the file writing logic. This change improves readability and maintainability by ensuring that header files are generated before the presym list, thus eliminating the need for explicit existence checks.

Highlights

Simplified Logic: The logic for generating presym files has been simplified by consolidating file output operations into a single conditional block, removing redundant checks.
Removed Redundancy: The explicit update variable and checks for the existence of header files before writing have been eliminated, streamlining the process.
Improved Order of Operations: The order of operations was adjusted to write header files before the presym list, which inherently removes the need to check for header file existence.
