[webauthn] Per TCG: "privacy CA" is now "Attestation CA"

equalsJeffH has just created a new issue for https://github.com/w3c/webauthn:

== Per TCG: "privacy CA" is now "Attestation CA" ==
Note that if one searches the TCG's  TPM 2.0 specs for "privacy CA", one will not find it. 

I went looking and found this in https://trustedcomputinggroup.org/wp-content/uploads/IWG_CMC_Profile_Cert_Enrollment_v1_r7.pdf

>2.2 Attestation CA
The primary Certification Authority (CA) associated with the TPM has been referred to in previous TCG publications as either the “Privacy CA” (PCA) or “Platform CA”. In an effort to separate the issues of privacy from those of attestation, that designation is replaced here with the term “Attestation CA” (ACA). The role and operation of the ACA is described in detail in section 3, below.

Indeed "attestation CA" is used in e.g. in [TPM 2.0 Part 1 Architecture](https://trustedcomputinggroup.org/wp-content/uploads/TPM-Rev-2.0-Part-1-Architecture-01.38.pdf).
