[boost-uninstall] Add port to easily uninstall all boost components

[JackBoosY]

Since boost contains three additional installation function ports(boost-build, boost-vcpkg-helpers, boost-modual-build-helper), removing all boost components requires the following three steps:

1. ./vcpkg remove boost-vcpkg-helpers --recurse
2. ./vcpkg remove boost-modular-build-helper
3. ./vcpkg remove boost-build

Add a port to easily uninstall all boost components using the following command:

./vcpkg remove boost-uninstall --recurse

The correct way to do this is to make all ports depend on boost-build because that is the only way to generate the config.cmake in the future

[JackBoosY]

@Neumann-A It is not obvious to use boost-build, and the remaining two ports are also providing other configuration files.

What about uses of boost that only need the headers and therefore don't need to build boost.build?

[Neumann-A]

@BillyONeal also applies to header only. Think of boost.build as boost.cmake. boost.build just defines install rules and one of the rules is to install configs. Since boost has a header target in cmake it requires to generate a config for it.

@Neumann-A

1. As I said, boost-vcpkg-helpers and boost-modular-build-helper provides some other scripts and may be updated in the future, so I think we also need to remove them.
2. Totally remove boost using boost.build is not a good choice, because its name cannot represent boost as a whole.

We may need to add a new keyword Components to CONTROL or the manifest and use it to notify vcpkg to delete all related components when deleting port which have it.

[BillyONeal]

This is fine because it doesn't cause 'damage' but it would be nice to solve this more generally, such as one of the following solutions:

• Make the remove command support wildcards (such as continuing from Make "remove" accept regular expressions #8575 )
• An alias ports feature added such that vcpkg install boost installs all the boost packages and vcpkg remove boost would remove them all (without --recurse)

@JackBoosY Do you want to try one of those or just merge this for now?

[JackBoosY]

@BillyONeal Just merge this PR temporary would be okay.
