TPM/TXT auto-unseal

**Is your feature request related to a problem? Please describe.** HSMs are expensive and require Vault Enterprise. KMS solutions only work in the cloud. TPM-based auto-unseal would allow for auto-unseal based on measured boot. **Describe the solution you'd like** Vault should support unsealing via a TPM. **Describe alternatives you've considered** None **Explain any additional use-cases** This would be useful for those who want to run Vault on a bare-metal server, especially individuals for whom the cost of an HSM and/or Vault Enterprise would be difficult to justify. In home lab situations, automatic unseal after power outages is important. **Additional context** It would also be nice if the TPM could be used for the server certificate or (more likely) for decrypting its secret key.
