Conversion of compiler option guide to machine readable format

[mayank-ramnani]

In the future, there might be tools based on the OpenSSF compiler options guide.
This issue is a tracker to make the guide suitable to be converted into a machine readable format like json.
Tools such as the one I am working on (https://github.com/mayank-ramnani/temper) need the options in a machine readable format to do processing using them.

Currently, the guide has some inconsistencies which make it difficult to convert to a machine readable format.

Some issues in parsing:

1. Non-standard table format:

• There are only a few rows in which the column “Compiler Flag” contains additional data other than the flag:
• Example:

-D_FORTIFY_SOURCE=3
(requires -O1 or higher,
may require prepending -U_FORTIFY_SOURCE)

• Suggestion: Move the additional details to another column, maybe to description. Have a standard table format.

2. Non-standard version mentions.

• Suggestion: Mention till patch version (ex: gcc 2.95.3) instead of just the major version (ex: gcc 12)

I will update this thread with more insights and can create a PR that implements the above.

The script I created to scrape the webpage and convert it to json: doesn't give perfect results due to inconsistencies in the guide - https://github.com/mayank-ramnani/temper/blob/main/extra/scraper.py
