TT#115002 Do not wrap lines in i18n POT, PO files

Translation files (*.po) come from Crowdin platform in not wrapped
format. Let's not break the lines on our side, so that it will be easier
to analyze translation changes and also will not generate unnecessary
commits and false commit differences.

Add the '--no-wrap' flag to tell xgettext, msgattrib and msgmerge
programs not to split long lines into several lines.

Normalize the English source POT file with msgattrib utility right after
running xgettext.pl that creates duplicates of context filenames and
does not support the xgettext attribute ‘--width’.

Use the '--width=100000' parameter as a workaround for context filename
lines that continue to be wrapped despite the ‘--no-wrap’ flag.
