Feature Request: `editor.autoCloseBlockComment` setting

In `language-configuration.json`, block comment start and end positions can be defined. For example, for cpp, or typescript-basics: ``` "blockComment":["/*","*/"] ``` typescript-basics also has an AutoClosingPair defined for block comments (requiring an additional asterisk, though I'm not aware of the origin of that convention) : ``` { "open": "/**", "close": " */", "notIn": [ "string" ] } ``` There are currently two settings, which make it possible to disable the auto-closing, for brackets and quotes: `editor.autoClosingBrackets` and `editor.autoClosingQuotes`. It looks like `editor.autoClosingBrackets` also controls whether comments are auto-closed. Since there are fields in `language-configuration.json` to identify brackets and blockComments, it seems enabling/disabling of block comments could be done using a separate setting, rather than being lumped in with brackets. There is not currently an `autoClosingPair` in `cpp`. I'd also like to suggest adding that, provided there is a way to disable it without disabling auto closing of brackets. Alternatively, if there is a recommended way of implementing auto-closing of block comments that could be implemented by an extension, perhaps we could do that in the C/C++ extension and provide our own setting for it. Ideally, C++ block comment closing would not require the second asterisks (required in typescript* and the closing `*/` could be typed over.
