Remove JSHint due to license compatibility
Backports [42547] without adding new files due to how minor updates work.
JSHint inherits a license from JSLint that includes the clause "The Software shall be used for Good, not Evil." WordPress's license specifically allows grants the freedom to run the program, for any purpose. Please note, this is not an encouragement of evil. Rather than doing something evil, how about learning to love those around you. Instead of tweeting lies and saying people are "Not Good!", help your neighbor. In the words of Lin Manual Miranda, "Love is love is love is love is love is love is love is love, cannot be killed or swept aside."
This replaces JSHint with esprima, a part of the larger jQuery project, and a custom wrapper for some basic error checking within codemirror.
The existing JSHint configuration is kept in place in case someone wants to use that, but they can only do so for Good.
Fixes #42850
Props netweb for a spelling fix on a comment.

// When an assignment expression position starts with an left parenthesis, the determination of the type
// of the syntax is to be deferred arbitrarily long until the end of the parentheses pair (plus a lookahead)
// or the first comma. This situation also defers the determination of all the expressions nested in the pair.
//
// There are three productions that can be parsed in a parentheses pair that needs to be determined
// after the outermost pair is closed. They are:
//
// 1. AssignmentExpression
// 2. BindingElements
// 3. AssignmentTargets
//
// In order to avoid exponential backtracking, we use two flags to denote if the production can be
// binding element or assignment target.
//
// The three productions have the relationship:
//
// BindingElements ⊆ AssignmentTargets ⊆ AssignmentExpression
//
// with a single exception that CoverInitializedName when used directly in an Expression, generates
// an early error. Therefore, we need the third state, firstCoverInitializedNameError, to track the
// first usage of CoverInitializedName and report it when we reached the end of the parentheses pair.
//
// isolateCoverGrammar function runs the given parser function with a new cover grammar context, and it does not
// effect the current flags. This means the production the parser parses is only used as an expression. Therefore
// the CoverInitializedName check is conducted.
//
// inheritCoverGrammar function runs the given parse function with a new cover grammar context, and it propagates
// the flags outside of the parser. This means the production the parser parses is used as a part of a potential
// pattern. The CoverInitializedName check is deferred.

Editor: Add CodeMirror-powered code editor with syntax highlighting, linting, and auto-completion.
* Code editor is integrated into the Theme/Plugin Editor, Additional CSS in Customizer, and Custom HTML widget. Code editor is not yet integrated into the post editor, and it may not be until accessibility concerns are addressed.
* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.
* The CodeMirror library is included as `wp.CodeMirror` to prevent conflicts with any existing `CodeMirror` global.
* An `wp.codeEditor.initialize()` API in JS is provided to convert a `textarea` into CodeMirror, with a `wp_enqueue_code_editor()` function in PHP to manage enqueueing the assets and settings needed to edit a given type of code.
* A user preference is added to manage whether or not "syntax highlighting" is enabled. The feature is opt-out, being enabled by default.
* Allowed file extensions in the theme and plugin editors have been updated to include formats which CodeMirror has modes for: `conf`, `css`, `diff`, `patch`, `html`, `htm`, `http`, `js`, `json`, `jsx`, `less`, `md`, `php`, `phtml`, `php3`, `php4`, `php5`, `php7`, `phps`, `scss`, `sass`, `sh`, `bash`, `sql`, `svg`, `xml`, `yml`, `yaml`, `txt`.

Remove JSHint due to license compatibility
Backports [42547] without adding new files due to how minor updates work.
JSHint inherits a license from JSLint that includes the clause "The Software shall be used for Good, not Evil." WordPress's license specifically allows grants the freedom to run the program, for any purpose. Please note, this is not an encouragement of evil. Rather than doing something evil, how about learning to love those around you. Instead of tweeting lies and saying people are "Not Good!", help your neighbor. In the words of Lin Manual Miranda, "Love is love is love is love is love is love is love is love, cannot be killed or swept aside."
This replaces JSHint with esprima, a part of the larger jQuery project, and a custom wrapper for some basic error checking within codemirror.
The existing JSHint configuration is kept in place in case someone wants to use that, but they can only do so for Good.
