Also sync help texts for the option between elf and coff ports.

Decisions:

- Do this even if /lldignoreenv is passed. /linkrepro: does not affect the main output, and this makes the env var more convenient to use. (On the other hand, it's now possible to set this env var and forget about it, and all future builds in the same shell will be much slower. That's true for ld.lld, but posix shells have an easy way to set an env var for a single command; in cmd.exe this is not possible without contortions. Then again, lld-link runs in posix shells too.)

- Call the env var LLD_REPRODUCE like in ld.lld even though the flag is called /linkrepro: instead of --reproduce in lld-link.
