Merge bitcoin/bitcoin#23512: policy: Treat taproot as always active 
fa3e0da06b policy: Treat taproot as always active (MarcoFalke)

Pull request description:

  Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:

  * Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
  * Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.

  A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .

  This effectively reverts commit c5ec0367d7.
