Chrome & Firefox now support complex `:not()` selectors so those test can run
in them even without custom jQuery selector code. In the past, it was only
possible in Safari, now we only need to exclude IE.
Closes gh-4864
Drop support for Edge Legacy: the non-Chromium, EdgeHTML-based Microsoft
Edge version. Also, restrict some workarounds that were applied
unconditionally in all browsers to run only in IE now. This slightly
increases the size but reduces the performance burden on modern browsers
that don't need the workarounds.
Also, clean up some comments & remove some obsolete workarounds.
Fixes gh-4568
Closes gh-4792
Remove the workaround for a broken `:enabled` pseudo-class on anchor elements
in Chrome <=77. These versions of Chrome considers anchor elements with the
`href` attribute as matching `:enabled`.
Closes gh-4569
qSA in IE 11/Edge often (but not always) don't find elements with an empty
name attribute selector (`[name=""]`). Detect that & fall back to Sizzle
traversal.
Interestingly, IE 10 & older don't seem to have the issue.

Closes gh-4510
Sizzle's PR jquery/sizzle#456 introduced a test catching not throwing on
badly-escaped identifiers by Firefox 3.6-5. Unfortunately, it was placed just
before a test Opera 10-11 failed, making Opera fail quicker and not adding
a post-comma invalid selector to rbuggyQSA.
The issue was fixed in jquery/sizzle#463. This jQuery commit backports the test
that Sizzle PR added as no workarounds are needed in browsers jQuery supports.
Closes gh-4516

With new selector code doing less convoluted support tests, it was possible
to extract a lot of logic out of setDocument & also reduce size.
This commit also backports jquery/sizzle#439 that was reverted by mistake
during a switch from JSHint + JSCS to ESLint.

The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome,
Firefox & Safari have supported if for a long time; only IE & Edge lack support.
This commit leverages this pseudo-class to get rid of the ID hack in most cases.
Adding a temporary ID may cause layout thrashing which was reported a few times
in [the past.
We can't completely eliminate the ID hack in modern browses as sibling selectors
require us to change context to the parent and then `:scope` stops applying to
what we'd like. But it'd still improve performance in the vast majority of
cases.

This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The selector-native module has been removed. Further work on the selector
module may decrease the size enough that it will no longer be necessary. If
it turns out it's still useful, we'll reinstate it but the code will look
different anyway as we'll want to share as much code as possible with
the existing selector module.
The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are
sorted by their first contributions to either of the two repositories.
The commit reduces the gzipped jQuery size by 1460 bytes compared to master.
Closes gh-4395
Apart from porting most Sizzle tests to jQuery (mostly to its selector module),
this commit fixes selector-native so that a jQuery custom compilation that
excludes Sizzle passes all tests as well.
Closes gh-4406
Also, run `grunt npmcopy` to sync the "external" directory with dependencies
from package.json. For example, the Sinon library version didn't match.
