Previously, all.bash and all.bat restored the original $PATH before
calling 'dist banner', so that it would do its job of checking whether
the user still needs to add $GOROOT/bin to their $PATH. That worked for
those scripts, but had no effect on make.bash nor make.bat.
Instead of trying to extend that logic to more scripts, change the
approach to provide dist an unmodified copy of $PATH via an internal
to dist environment variable $DIST_UNMODIFIED_PATH. The make.bash and
make.bat scripts happen to use dist env -p to modify $PATH, making it
viable to add the internal variable there instead of in each script.
It currently works by adding semicolon terminators to dist env output
so that make.bash's 'eval $(dist env -p)' works as before but is able to
export DIST_UNMODIFIED_PATH for following dist invocations to observe.
Nothing needs to be done for Windows since its 'set ENV=val' format
already has that effect.
Plan 9 doesn't use the -p flag of dist env, and checks that GOROOT/bin
is bound before /bin rather than looking at the $PATH env var like other
OSes, so it may not have this bug. I don't have easy access to Plan 9
and haven't tried to confirm.
Fixes #42563.

This is a followup to CL 96495.
It should be simpler and more robust to achieve .bat files having
CRLF line endings by treating it as a binary file, like all other
files, and checking it in with the desired CRLF line endings.
A test is used to check the entire Go tree, short of directories
starting with "." and named "testdata", for any .bat files that
have anything other than strict CRLF line endings. This will help
catch any accidental modifications to existing .bat files or check
ins of new .bat files.
Importantly, this is compatible with how Gerrit serves .tar.gz files,
making it so that CRLF line endings are preserved.
The Go project is supported on many different environments, some of
which may have limited git implementations available, or none at all.
Relying on fewer git features and special rules makes it easier to
have confidence in the exact content of all files. Additionally, Go
development started in Subversion, moved to Perforce, then Mercurial,
and now uses Git.¹ Reducing its reliance on git-specific features will
help if there will be another transition in the project's future.
There are only 5 .bat files in the entire Go source tree, so a new one
being added is a rare event, and we prefer to do things in Go instead.
We still have the option of improving the experience for developers by
adding a pre-commit converter for .bat files to the git-codereview tool.

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

we need to restore %PATH% before calling "dist banner", so that
it could suggest the user to add %GOROOT%/bin to %PATH% if necessary.
