Subject: feat(fmt): add support for configuration file (#11944)

This commit adds support for configuration file for "deno fmt"
subcommand. It is also respected by LSP when formatting
files.

Example configuration:
{
    "fmt": {
        "files": {
            "include": ["src/"],
            "exclude": ["src/testdata/"]
        },
        "options": {
            "useTabs": true,
            "lineWidth": 80,
            "indentWidth": 4,
            "singleQuote": true,
            "textWrap": "preserve"
        }
    }
}
