Marc Mutz f29566c5a4 Prevent repeated instantiations of some qRegisterNormalizedMetaType<>s [1/N] (QtGui) 
Create macros that wrap the magic developed in
7d63efc16f and apply it to all
Q_DECLARE_METATYPE invocations that show up in Clang -ftime-trace for
a PCH'ed QtGui build.

Effects on compile times:

Clang 10 -ftme-trace:

  $ ClangBuildAnalyzer --analyze qtgui-before.trace  | head -n6
  Analyzing build trace from 'qtgui-before.trace'...
  **** Time summary:
  Compilation (523 times):
    Parsing (frontend):          628.3 s
    Codegen & opts (backend):    304.5 s

  $ ClangBuildAnalyzer --analyze qtgui-after.trace  | head -n6
  Analyzing build trace from 'qtgui-after.trace'...
  **** Time summary:
  Compilation (523 times):
    Parsing (frontend):          546.0 s
    Codegen & opts (backend):    304.4 s

GCC 11 time (bash builtin):
