* Introduce helper for formatting PCR selection bitmasks

This change introduces PCClientCompatible.PCRs(), a function that
converts a variadic list of PCR indices (as ints) into a PCR selection
bitmask. Because of the vagaries of TPM:

1. That the minimum size of a PCR selection bitmask is not 0, but
   related to the minimum number of PCRs specified by the profile
2. That the PC Client Platform TPM Profile specification mandates a
   minimum but not a maximum number of implementation PCR,

this change creates an interface that could be implemented for other TPM
profiles that specify different amounts of PCRs. The vast majority of
on-market TPMs will just work with PCClientCompatible.PCRs, even if they
implement more than 24 PCRs.

PCRs() can panic if given invalid values; this is to allow it to be
inlined into the definition of a structure that needs a PCR selection.

* Don't publish the interface for the PCR selection formatter just yet.

* use uint instead

`TPMUSignature.ECDAA()` incorrectly checked whether 
the signature algorithm is `RSASSA`, so this commit fixes it.

Update: `TPMAlgRSASSA` => `TPMAlgECDAA`

* Add TPM2_HMAC_Start implementation

- See definition in Part 3, Commands, section 17.2

* Review: change transient constant naming

* Review: change transient handle Name computation

* Fix Docker go version to match linter dependencies

* Bump go to 1.22 and golangci-lint to 1.56.2

* Use single assignment of ECC curve in test
