security: Add new TPM framework
The TPM framework is separated into two parts:
1) The front end class Tpm provides the interface to KeyChain. The public
interface of Tpm is read-only.
2) The back end classes represent concrete implementations, such as
tpm::BackEndFile and tpm::BackEndOsx which may also provide
implementation-specific management interfaces.
New TPM supports different key id type when generating new key. The
default type is changed to 64-bit random number.
