Index on WID+memberID in SvxItemPropertySet::aCombineList

...instead of just WID.  For example when loading
caolan/sdrobject_getmergeditemset_null_ptr_dereference.sample (from the
crashtestdata files) under UBSan,

would first store an Any with value sal_Int32 -1 (representing an RGBA
255/255/255/255 color) in aCombineList for property CharUnderlineColor with
WID = EE_CHAR_UNDERLINE = 4027 and member-ID = MID_TL_COLOR = 2, but then read
back out that Any for property CharUnderline with the same WID but member-ID =
MID_TL_STYLE = 1 and use it at
