  Log Message:
  -----------
  Boost CMake modernization (#1330)

* Remove FindBoost.cmake

Use the one provided by CMake so we don't have to maintain this one.

* Remove from-source build

* Remove user-configurable version

* Force use of multithreaded libraries

We don't need to include Threads here. Boost will do that.

* Disable use of statically-linked runtime

* Remove Boost_DEBUG

* Always enable searching system paths

* Unify path calculations, pass to find_package as hints

* Clean up comments

* Use include_guard

* Allow using Boost's CMake package

It is now provided by default since 1.70.0 which is the current minimum
acceptable version.

* Remove rest of cache variables

* Remove MSVC-specific template define

We can add this back, if we find there are newer VCs still affected.

* Make Dyninst::Boost imported interface target

This is needed to make the include directories be "system" directories
so that warnings in their headers do not propagate into Dyninst.

* Do not add Boost as a dependency for all libs

* Make find_package QUIET

* Use Boost_* variables instead of calculating includes, libs, etc.

* Make a header-only wrapper target

* Add to Dyninst package

* Update CMakeLists

* Whitespace formatting

* Set Boost_NO_WARN_NEW_VERSIONS

* Bump minimum version to 1.71.0
