Marc Hartmayer 938fe2a744 rust/utils: Add AtomicFile
This type helps to perform atomic operations by writing to a temporary
file and renaming it to the actual filename when the
`AtomicFile::finish` function is called. If the `AtomicFile::finish`
function is never called, the temporary file is automatically removed
when it goes out of scope. It utilizes the `renameat2` [1] libc function
and its semantics.

Add additional data for the Attestation request. The secret store hash
measures all added secrets and the state of the store (locked or not)

locked, 0 for not locked). The firmware state is an opaque state
description of the systems firmware status to be interpreted by an IBM
service. Add request flags and fields in the additional data structure.
