Rework the extension test macros section #57

This attempts to rework the extension test macros section and drop the useless (and incomplete) extension test macro list.
Previous attempts to clean up this section can be found in #27 and #28.

This should avoid the need for PRs like #55 that add something obvious done by GCC and LLVM without the need for this list. Further, we recently also discussed this in the context of #44 (adding bitmap and scalar crypto extensions to the list). So I think it is time to remove the list.

We have a list of macros, that should be extended for each new
extension. Let's rephrase the section such, that the wording
targets all extensions that are supported by compilers and
remove the incomplete list.

For what it's worth, looks good to me. Definitely better than an incomplete list of extensions.

LGTM, apparently I missed this PR somehow, anyway thanks for improving this section, I just got asked around XXX extension has marco to check or not, and every time I point I point to here, I also need spend time to explain the table isn't up to date too, so I think just dropping whole table can make people less confusion (on why XXX extension is not list their) at first time.
