[feature] use short_paths during build, normal paths during packaging

[madebr]

Some packages need short_paths enabled during build, but once built can be stored normally in a package folder in CONAN_HOME.
For example conan-io/conan-center-index#725,
this package needs short_paths enabled during build() but can have a normal path during package().

Essentially, it would be nice if self.build_folder can be a short path but self.package_folder a normal path.

• I've read the CONTRIBUTING guide.

The short_paths feature is a bit of a mess, complicated and fragile. I am proposing in https://github.com/conan-io/conan/pull/6415/files some possibility to try to improve it.

This feature request makes sense, but I am a bit afraid of adding more complexity and fragility into the code, for something that doesn't seem critical, but a nice to have. I would delay this to see if https://github.com/conan-io/conan/pull/6415/files moves forward, and come back later to analyze if makes sense or not. A possibility could be allowing defining short_paths = "build", and short_paths = "build", "package" or something like that.

It sounds good, any user will be able to decide what they want.

This would be nice.
Also, I think adding source as an option would be interesting. This might benefit no_copy_source = True builds.

short_paths removed in Conan 2.0, closing this ticket as outdated.
