configure: CMake: Add -no-prefix option
Introduce a new -no-prefix option that can be used to build Qt without
having to install it.
Currently, -no-prefix is already implied by -developer-build, but
-developer-build also implies -warnings-are-errors and
-feature-private-tests, which not everyone might want to use.
Some Qt builders likely use -developer-build for the no-prefix
behavior, hence we introduce a standalone -no-prefix option to offer
a nicer user experience without -Werror and friends.
Previously it was possible to achieve the same by specifying
-prefix $PWD, but that relies on $PWD expanding property in the used
shell.
The new -no-prefix doesn't depend on the type of the shell and
is shorter to type.
Internally this gets passed by configure as -DINPUT_no_prefix=yes to
CMake, and transformed into a -DQT_FEATURE_no_prefix=ON feature.
The feature also gets automatically auto-detected to ON if
developer-build is set, -prefix is either unset or $PWD.
CMake code should still query QT_WILL_INSTALL to decide whether
files need to be installed or not.
As a drive-by, we now also export QT_FEATURE_developer_build to
be available for querying during configuration of other repos
(previously it was only possible to query FEATURE_developer_build).
Pick-to: 6.2 6.3
