dependencies: allow get_variable to expose files from subprojects There are somewhat common, reasonable and legitimate use cases for a dependency to provide data files installed to /usr which are used as command inputs. When getting a dependency from a subproject, however, the attempt to directly construct an input file from a subproject results in a sandbox violation. This means not all dependencies can be wrapped as a subproject. One example is wayland-protocols XML files which get scanned and used to produce C source files. Teach Meson to recognize when a string path is the result of fetching a dep.get_variable(), and special case this to be exempt from subproject violations. A requirement of this is that the file must be installed by install_data() or install_subdir() because otherwise it is not actually representative of what a pkg-config dependency would provide.

sub1_d = subproject('subproj1').get_variable('d')
sub1_mustfail = sub1_d.get_variable('dir') / '..' / 'file.txt'
sub2_d = subproject('subproj2').get_variable('d')
sub2_mustfail = sub2_d.get_variable('dir') / 'file.txt'
dependencies: move DependencyVariableString handling to declare_dependency This allows tracking which subproject it came from at the time of definition, rather than the time of use. As a result, it is no longer possible for one subproject which knows that another subproject installs some data files, to expose those data files via its own declare_dependency.
