rust/pv: Refactor pv crate

Big refactoring patch of the pv crate. The main reason behind this
refactoring is to simplify testing and maintaining the pv crate while
keeping OpenSSL/libcurl dependencies optional. Using crate features
increases the number of targets that have to be tested. This refactoring
eliminates the use of features by splitting the functionality of pv into
a use OpenSSL and no-use-OpenSSL crate.

Split off some code from the pv crate into a pv_core crate. pv requires
pv_core and reexports all symbols. pv_base contains all code from former
pv that does not use OpenSSL or libcurl functionalities. The refactored
pv crate contains functionalities to generate requests and validate host
key documents. All features from pv are dropped as they are not needed
anymore and to streamline the codebase for easier use and testing. While
at it fix some documentation issues.

Users (pvsecret & pvapconfig) have next to no code change, besides the
different import of the crate.

## Internal Libraries
* __utils__ _Library for rust tools that bundles common stuff for the 390-tools_
* currently only provides a macro to get the `S390_TOOLS_RELEASE` string
* provides a macro to get the `S390_TOOLS_RELEASE` string
* provides macros for compile time assertions
* __pv_core__ _Library for pv tools, providing uvdevice access and utilities to send, receive and interpret various UV-calls._
* __pv__ _Library for pv tools, providing uvdevice access, encryption utilities, and utilities for generating UV-request_
* requires openssl and libcurl for the feature `request`; use `HAVE_<OPENSSL|CURL>=0` to
disable build that use pv with the request feature.
* requires openssl and libcurl
* reexports ann symbols from __pv_core__
* if no encryption utilities required, use __pv_core__
## Tools
* __pvsecret__ _Manage secrets for IBM Secure Execution guests_
* requires pv with the `request` feature
## Writing new tools
We encourage to use Rust for new tools. However, for some use cases it makes
