Revert "[analyzer] Model strchr/strrchr/memchr/strstr/strpbrk/strchrnul (#207267)"
This reverts commit a34cb573eae65f48f0e51147289e042a86b55d16.
This feature caused some issues (#209905), so the best course of
action is to postpone it to clang-24 and revert from this branch.
The #210154 tried to fix the surfaced issue, and considered to nominate
it for backport in #211832, but ultimately we had to revert it from
main in #211857 - this confirms that probably the best action is to
revert the half-baked feature from the release branch.
This means that #203260 won't be fixed in clang-23, and that's fine.
