[Build] Extend PCH to libraries and grow IWYU-driven header sets (#7456)
The executables precompile Qt since #7235, but the libcockatrice_*
static libraries still reparse the full Qt Core stack in every TU.
Measured over the tree after the IWYU pass: 380 MB of header parse in
the libraries, 92% of it reachable from qtcore_pch.h.

- Apply qtcore_pch.h to the 14 Qt Core static library targets
  (skips libcockatrice_rng: its SFMT.c is C and cannot use a C++
  precompiled header).
- Grow qtcore_pch.h with 25 QtCore headers that IWYU shows are
  re-parsed across many TUs and were not already reachable from the
  existing list (JSON/QUuid cluster, QSettings, item models,
  threading, XmlStream, QTemporaryDir, ...).
- Grow qtwidgets_pch.h with 30 QtGui/QtWidgets headers (dialog
  cluster, item views, QImageReader, ...).

Only stable Qt headers go into the PCH, so it rarely invalidates.
Test executables stay PCH-less: 1-3 TUs per target does not amortize
the extra precompile.

/** @file qtwidgets_pch.h
* @brief Precompiled header for GUI targets (Cockatrice client, Oracle).
*
* Includes the Qt Core precompiled header plus the heavy Gui, Widgets and
* Network layers that virtually every client translation unit re-parses.
* Do not use on Servatrice (headless, QT_DONT_USE_QTGUI).
*
* Candidates are chosen from IWYU include statistics: a header earns a
* spot when it is not already reachable from the rest of this list and
* enough translation units re-parse it. Qt headers are stable across
* builds, so the precompiled header rarely invalidates.
