Giovanni Bajo 787e7b048c build: force all Windows batch files to CRLF
Batch files should use CRLF endings. LF endings mostly
work but in some situations they cause random errors like
goto commands failing for mysterious reasons. See
golang.org/issue/37791 for more information.

Next CL triggered one of such bug (a label was not being
recognized), so prepare for it by converting to CRLF.

This CL also touches all existing batch files to force git
to update the line endings (unfortunately, changing
.gitattributes only has effect next time the file is checked
out or modified).

Fixes #37791
Updates #9281
