Migrate all source AMD modules to ECMAScript modules. The final bundle
is compiled by a custom build process that uses Rollup under the hood.
Test files themselves are still loaded via RequireJS as that has to work in
IE 11.
Tests can now be run in "Load as modules" mode which replaces the previous
"Load with AMD" option. That option of running tests doesn't work in IE
and Edge as it requires support for dynamic imports.
Some of the changes required by the migration:
* check `typeof` of `noGlobal` instead of using the variable directly
as it's not available when modules are used
* change the nonce module to be an object as ECMASscript module exports
are immutable
* remove some unused exports
* import `./core/parseHTML.js` directly in `jquery.js` so that it's not
being cut out when the `ajax` module is excluded in a custom compilation

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.

This commit requires all function parameters to be used, not just the last one.
In cases where that's not possible as we need to match an external API, there's
an escape hatch of prefixing an unused argument with `_`.
This change makes it easier to catch unused AMD dependencies and unused
parameters in internal functions the API of which we may change at will, among
other things.
Unused AMD dependencies have been removed as part of this commit.

1. Use the short name of the preset in the config.
2. Run ESLint first on non-minified files.
3. Explicitly specify environments in every config file (those settings cascade
which means we've been assuming a Node.js environment where we shouldn't have).
