Switch eng/common to linguist-vendored

[rainersigwald]

This is a more accurate description of what's going on here; the code canonically lives in dotnet/arcade and so is vendored here.

@benvillalobos I'd like to merge this ASAP because it will make reviewing #5836 easier :)

@rainersigwald this modifies PR reviews as well? I read the docs as it applying more to the stats on our repo page for languages.

That's . . . a really good question. I read it that way but maybe not? Checking now.

Looks like we need both; see https://github.com/rainersigwald/msbuild/pull/4/files

LGTM. This is a cool feature, effectively hiding all irrelevant changes. I kinda wish it would highlight that better, IIRC the message Some generated files are not rendered by default. Learn more. looks similar to the message about how some diffs are too big . So it could easily be mistaken.

@rainersigwald should we consider adding linguist-generated to everything under ref/? Had this idea when looking over #5936. If so, should be considered "low priority quality of life change"

While we're at it, src/Build/Resources/xlf to auto-hide generated resources would be nice
