Require at least Boost 1.71, support Boost 1.86, switch to BoostConfig.cmake

Remove warning about old policy in CMake 3.30: https://cmake.org/cmake/help/latest/policy/CMP0167.html#policy:CMP0167
BoostConfig.cmake is available in Boost 1.70 and higher. With BoostConfig.cmake, it is no longer necessary to keep Boost_ADDITIONAL_VERSIONS updated.
Ubuntu 20.04 uses Boost 1.71.0 as the default version (Boost 1.67 is available but not the default).

We probably need to use a newer commit hash for vcpkg on x86 - the boost-cmake package quite new. microsoft/vcpkg@bcf3d00

[mvieth]

Ah yes, you are right. Which one should we choose? The latest commit on the vcpkg master branch? Or the one where boost-cmake was just added?

Since x86 should use the oldest version possible, I think we should opt for the oldest tag, that the commit is within, ie https://github.com/microsoft/vcpkg/releases/tag/2024.05.24 which commit hash: 01f602195983451bc83e72f4214af2cbc495aa94

Suggested change

	VCPKGCOMMIT: 01f602195983451bc83e72f4214af2cbc495aa94
	VCPKGCOMMIT: f7423ee180c4b7f40d43402c2feb3859161ef625

There was a problem with the hashes with the boost port, seems like we have to use release 2024.06.15 instead.

Do we need to split out the docker updates, as its only pushed when build on merge?

I can do that, yes. It would be the safer approach, otherwise we would have no guarantee that the Windows x86 CI turns green with the new Docker image.

Suggested change

	find_package(Boost 1.71.0 ${QUIET_} COMPONENTS @PCLCONFIG_AVAILABLE_BOOST_MODULES@ CONFIG)
	find_dependency(Boost 1.71.0 COMPONENTS @PCLCONFIG_AVAILABLE_BOOST_MODULES@ CONFIG)

Needs include(CMakeFindDependencyMacro) somewhere above.

Thanks for the suggestion, but that is a bit off-topic in this pull request, and I would like to merge this pull request as soon as possible because PCL's incompatibility with Boost 1.86 makes one of our CI checks fail. Perhaps we can look at find_dependency again in the future, in another pull request.
