Up to now `eslint-plugin-brace-rules` was used to enforce a common brace
style for JavaScript code. This plugin was however updated the last time
over 9 years ago and will be incompatible with ESLint v10, as that
[removes `context.getSourceCode()`][1], the plugin relies on.
To keep the eslint config working with ESLint v10, this replaces
`eslint-plugin-brace-rules` with the [`@stylistic/brace-style`][2] rule
from `@stylistic/eslint-plugin`, a package we already use.
While `@stylistic/brace-style` doesn't offer an option to format braces
in exactly the same way as before, the "allman" style seems to be the
one closest to the existing code.

`JSNatives` passed to SpiderMonkey must not throw exceptions. Most
callbacks are wrapped in `ScriptFunction::ToJSNative`.
This commit adds exception handling to `ScriptFunction::ToJSNative` so
that exceptions thrown in the wrapped callbacks are catched and rethrown
as JavaScript `Error`s.
Not all modules should be able to load all other modules. A predicate
function can to be passed to the `ScriptInterface`. That function
returns whether the module is allowed to loat the module. If no
predicate is passed in no modules can be loaded through that
`ScriptInterface`.
- With modules JavaScript code can be split up into multiple files. We
already implemented such a mechanism (`Engine.LoadLibrary`) in
multiple parts of the engine. The advantage of using modules is
that it's standart (JS-devs are familiar with it) and it doesn't
has to be implemented multiple times.
Note that `Engine.LoadLibrary` loads all files in a directory
while the new `import` only loads one file.
- With modules seemingly global variables are local to that
script/module. We already implemented such a mechanism
(`ScriptInterface::LoadScript`).
