[LLD] [COFF] Pick timestamps from the SOURCE_DATE_EPOCH variable (#81326)

The SOURCE_DATE_EPOCH environment variable can be set in order to get
reproducible build.

When linking PE/COFF modules with LLD, the timestamp field is set to the
current time, unless either the /timestamp: or /Brepro option is set. If
neither of them is set, check the SOURCE_DATE_EPOCH variable, before
resorting to using the actual current date and time.

See https://reproducible-builds.org/docs/source-date-epoch/ for reference
on the use of this variable.
