Emilio Cobos Álvarez 2223a8bee2 Bug 2054311 - Sort headers in xpcom/. r=xpcom-reviewers,nika
Automatically generated with:

    cp dom/.clang-format xpcom/ && mach format xpcom/**.{cpp,h}

Manual changes:

 * nsTDependentSubstring.cpp was relying on include order, prevent that
   from being changed by clang-format.
 * Missing nsAtom.h include from nsGkAtoms.h
 * nsWindowsHelpers.h needed to keep the include order
 * MemoryPressureLevelMac.h needed mozilla/Attributes.h
