[ELF] Consistently use gotEntrySize for GOT entries (#142064)

d62413452fc6 ("[lld][X86] Restore gotEntrySize.") (re-)introduced
gotEntrySize and used it for various GOT calculations, but was not
exhaustive (nor consistent; Symbol::getGotOffset was modified but not
GotSection::finalizeContents, so we undercompute the size, on top of
computing the wrong offsets for TLS), and since then even more uses have
been added that use wordsize instead of gotEntrySize (presumably due to
looking at the existing incorrect ones).

This doesn't really matter upstream, as the only architecture where the
two differ is X32, and from looking at the code it's not properly
supported (e.g. TLS relaxation assumes LP64 sequences), but downstream
in CHERI LLVM it does matter, as CHERI's pointers are more than just an
integer address (a machine word).

Note this ignores the special MipsGotSection; on MIPS, wordsize and
gotEntrySize are the same, CHERI-MIPS is no longer something we support
downstream and even when we did we didn't reuse that implementation.
