Revert "Enable algorithm filtering (#1333)"

[baentsch]

This reverts commit 9ba752e as not all downstream projects can handle limitation to NIST standardized algorithm set.

A related PR is #1350 to resolve CCI failures. The proposed merge order is this PR first, then #1350.

• [no] Does this PR change the input/output behaviour of a cryptographic algorithm (i.e., does it change known answer test values)? (If so, a version bump will be required from x.y.z to x.(y+1).0.)
• [yes -- reverting back to previous behaviour] Does this PR change the the list of algorithms available -- either adding, removing, or renaming? Does this PR otherwise change an API? (If so, PRs in oqs-provider, OQS-OpenSSL, OQS-BoringSSL, and OQS-OpenSSH will also need to be ready for review and merge by the time this is merged.)
