Alexandru Croitor 5533eeeb01 CMake: Refactor parts of qt_internal_walk_libs
Refactor the function in preparation of processing rcc object files.

Introduce 2 new functions to get and set values in the memoization
dictionary used by qt_internal_walk_libs.

Modify qt_internal_add_target_aliases to assign the alias names it
creates as properties on the target.

Extract these aliases when available to assign memoized values not
only for the initial library name, but also for its aliases.

When recursively calling qt_internal_walk_libs, make sure to provide a
unique out_var name based on the outer target name, and not just
lib_libs. Otherwise the out_var values would be polluted from
previous recursion runs.

Make sure to check for -NOTFOUND in if() checks so that we reuse
memoized values that are the empty string.

#
# CMake allows changing the names of each of those pdb file types by setting

# See https://gitlab.kitware.com/cmake/cmake/-/issues/18393 for details.
#
# For shared libraries and executables, we install the linker provided pdb file via the

#
# For static libraries there is no linker invocation, so we need to install the compile
# time pdb file. We query the ARCHIVE_OUTPUT_DIRECTORY property of the target to get the
# path to the pdb file, and reconstruct the file name. We use a generator expression
# to append a possible debug suffix, in order to allow installation of all Release and
