Rebrand to hwtrust

Change the library from `libcert_request_validator` to `libhwtrust` and
the tool `bcc_validator` to `hwtrust`.

This renaming lets us use the components for all the hardware trust
related features and services we are building and continues the
deprecation of the term "BCC" in favour of "DICE chain".
