Added TZone annotations to X86_64 MacroAssembler.  Also filled out annotations for the MacroAssembler template class
tree including MacroAssemblerARM64E.  Needed to make the annotation for FixedVMPoolExecutableAllocator::Islands
conditional on ENABLE(JUMP_ISLANDS).  ASAN build found that bmalloc::Map had uninitialized members in the TZone paths,
so added a bmalloc::Map constructor to initialize its fields.  The X86 public SDK also found that the Printf
attributes for TZoneLog::osLogWithLineBuffer() needed fixing.
