[MTE] Disable all MTE protection of globals in sections (#78443)
Previous work in this area (#70186) disabled MTE in constructor
sections. Looks like I missed one, ".preinit_array".
Also, in the meantime, I found an exciting feature in the linker where
globals placed into an explicit section, where the section name is a
valid C identifer, gets an implicit '__start_<sectionname>' and
'__stop_<sectionname>' symbol as well. This is convenient for iterating
over some globals, but of course iteration over differently-tagged
globals in MTE explodes.
Thus, disable MTE globals for anything that has a section.
