Allow to specify import sorting.

Typescript has this long running issue full of complaints about how there's no way to prefer certain import paths over others, and in any non-trivially sized application, path aliasing is bound to clash with the various library imports available (hence the practice of having a path alias @/ to get at all first-party application imports).

https://github.com/microsoft/TypeScript/issues/51155

A plugin was suggested multiple times in the above issue, which has a very simple interface to configure around this: https://github.com/tidalhq/ts-plugin-sort-import-suggestions

I think this is something that should be included in tsgo itself, for two reasons:

• It's not just some fringe preference, everyone at some point will want to prefer certain import path prefixes over others
• It's an extremely simple thing to implement

I propose being able to add to tsconfig.json a configuration item like this:

{
  "compilerOptions": {
    "importSorting": {
        // Matches `@/`, `../` and `./`, move them up in the suggestions (This is the default config if you leave it empty)
        "moveUpPatterns": ["@/", "\\.{1,2}/"],
        // Move `dist` down in the suggestions, by default it's `[]`
        "moveDownPatterns": ["dist"],
    ]
  },
}

This is a flexible and performant approach that will handle pretty much everyone's needs. I don't know why this was left to be a plugin when it's such a critical piece of an ergonomic Typescript-based development environment.

先从链接的 TypeScript issue 和 ts-plugin-sort-import-suggestions 接口开始，然后定位 tsgo 对 import suggestion 的处理以及对 tsconfig.json 选项的解析。完成的标准是：某个编译器选项接受 moveUpPatterns 和 moveDownPatterns，并且 import suggestion 反映这些模式，同时为提议的示例提供覆盖。
