  [ELF][PPC32] Support .got2 in an output section description

I added `PPC32Got2Section` D62464 to support .got2 but did not implement .got2
in another output section.

PR52799 has a linker script placing .got2 in .rodata, which causes a null
pointer dereference because a MergeSyntheticSection's file is nullptr.
Add the support.
