I spent some time on enabling NLS on MSVC:

x86:

* x86 files are available here [1]. I downloaded 'Complete package,
except sources' from this page, installed it and set related bin_dir,
extra_include_dirst and extra_lib_dirs. Then I was able to compile
Postgres with nls being enabled. I did not run tests as it was taking
too much time on the Windows VM instance (not CI instance, regular
Google Cloud VM created by using our Windows CI images).

x64:

* I downloaded Dave Page's Windows gettext artifact from [2]. I am
able to configure Postgres with nls being enabled but then compilation
failed with:
