Modernize CMake code (ongoing refactoring) (#4507)
* Reformat CMake code

* Bump minimum CMake version to 3.12

* Add target sources separately via `target_source()`

* Make `tr_win32_app_info()` add target sources on its own

* Don't use `include_directories()`

* Don't use `add_definitions()`

* Limit use of `add_compile_options()`

* Move VDKQueue target declaration to a subdirectory

* Add `tr_disable_source_files_compile()` helper

* Add `tr_target_glib_resources()` helper

* Add `tr_gettext_msgfmt()` helper

* Enable AUTOUIC for Qt client

* Enable AUTORCC for Qt client

* Remove AUTO{MOC,RCC,UIC} source group overrides

* Add `tr_target_idl_files()` helper

* Move source group setup to `tr_qt_add_translation()`

* Add `tr_target_xib_files()` helper

* Prefer `target_sources()` to intermediate variables

* Use explicit visibility versions of `target_*()` commands

* Prefer genexes to conditions in `target_*()` commands

* Add `tr_allow_compile_if()` helper

* Leave only top-level `project()`, remove the rest

* Minor fixups

* Fixup Mac QL plugin install

* Fixup IDE target folders and source groups
