feature/tpm: protect all TPM handle operations with a mutex (#17708)
In particular on Windows, the `transport.TPMCloser` we get is not safe
for concurrent use. This is especially noticeable because
`tpm.attestationKey.Clone` uses the same open handle as the original
key. So wrap the operations on ak.tpm with a mutex and make a deep copy
with a new connection in Clone.

types/persist: add AttestationKey (#17281)
Extend Persist with AttestationKey to record a hardware-backed
attestation key for the node's identity.

Add a flag to tailscaled to allow users to control the use of
hardware-backed keys to bind node identity to individual machines.

Updates tailscale/corp#31269

types/key: add IsZero method to HardwareAttestationKey (#17370)
We will need this for unmarshaling node prefs: use the zero
HardwareAttestationKey implementation when parsing and later check
`IsZero` to see if anything was loaded.
