  [ELF] Move ElfSym into Ctx. NFC

Ctx was introduced in March 2022 as a more suitable place for such
singletons. ctx's hidden visibility optimizes generated instructions.

This change fixes a pitfall: certain ElfSym members (e.g.
globalOffsetTable, tlsModuleBase) were not zeroed and might be stale
when lld::elf::link was invoked the second time.
