only freeze require world age in processess generating output

Alt. to #28274. Fixes #28042.

Precompilation time of CSV before:

 42.693428 seconds (3.82 M allocations: 232.627 MiB, 0.33% gc time)

After:

 44.479788 seconds (3.83 M allocations: 233.338 MiB, 0.42% gc time)

Would be good if people could try locally as well.

Did you also compare the time for loading the precompiled package?

This does indeed fix the world age errors -- thanks @KristofferC :)

Performance does not seem to suffer too much from this.

With this fix:
precompiling CSV: 48.444573 seconds (4.84 M allocations: 281.981 MiB, 0.57% gc time)
using CSV: 1.787229 seconds (3.06 M allocations: 194.187 MiB, 11.02% gc time)

on 0.7.0-beta2.0:
precompiling CSV: 66.667827 seconds (4.72 M allocations: 293.743 MiB, 0.30% gc time)
using CSV: 2.267815 seconds (3.76 M allocations: 245.962 MiB, 7.88% gc time)

On master I get

julia> @time using CSV
  1.543129 seconds (2.98 M allocations: 191.424 MiB, 8.26% gc time)

with this PR (but on top of #28118 because that is what I had available) I get

julia> @time using CSV
  1.431326 seconds (2.86 M allocations: 185.156 MiB, 2.72% gc time)

Performance looks good on my machine. :)
