  [ELF] Move demoteSymbols to Writer.cpp. NFC

History of demoteSharedSymbols:

* https://reviews.llvm.org/D45536 demotes SharedSymbol
* https://reviews.llvm.org/D111365 demotes lazy symbols
* The pending #69295 will demote symbols defined in discarded sections

The pass is placed after markLive just to be clear that it needs `isNeeded`
information computed by markLive. The remaining passes in Driver.cpp do not use
symbol information. Move the pass to Writer.cpp to be closer to other
symbol-related passes.
