measure: strip tpm 1.x remnants and make GetActivePcrBanks() work (#39089)

Let's never bother with old TPM 1.x structures, they are not mentioned
in the TCG for TPM2 spec at all. However, the spec does say we should
check the Size field of the relevant structs, before accessing them,
hence do that.

Use that to determine the version of the protocol, before accessing
GetActiveBanks().

Alternative to: #39034
Fixes: #38932
