Issue:
Memory leak in the "no-unsupported-features" rule
<!--
  ❗Please don't ignore this template.❗

  If you ignore it, we're just going to respond asking you to fill it out, which wastes everyone's time.
  The more relevant information you can include, the faster we can find the issue and fix it without asking you for more info.
-->

<!--
  Before posting the issue, please confirm that the problem you're getting
  is not related with your code editor configuration.
  To make sure it's not, run: yarn eslint src/your-file.vue
-->

**Checklist**

- [x] I have tried restarting my IDE and the issue persists.
- [x] I have read the [FAQ](https://eslint.vuejs.org/user-guide/#faq) and my problem is not listed.
<!-- If you do not read the FAQ and open an issue that is listed in the FAQ, we may silently close the issue. -->

**Tell us about your environment**

- **ESLint version:** 7.32.0
- **eslint-plugin-vue version:** 7.20.0
- **Node version:** 14.16.0
- **Operating System:** macOS Catalina 10.15.7

Some additional details:
- Our project is relatively big – around 3000 `*.vue` files and around 2000 of `*.js` files with `// @vue/component` comment

**Please show your full configuration:**
<!-- Paste content of your .eslintrc file -->
```json5
{
    "root": true,
    "env": { "es2021": true },
    "plugins": ["vue"],
    "extends": ["plugin:vue/recommended"],
    "rules": {
        "vue/no-unsupported-features": ["error", { "version": "^2.6.14" }]
    }
}
```
*Note this is not full `.eslintrc` file, but just relevant part with the configured rule in question*

**What did you do?**	
<!-- Please include the actual source code causing the issue. -->
*No code here because this issue can be reproduced with both valid and invalid code.*

**What did you expect to happen?**
Memory consumption does not significantly change when `no-unsupported-features` rule is enabled.

**What actually happened?**
<!--
  Please include the actual, raw output from ESLint.
  If you are only looking at the results of your editor extension, also check the CLI results.
-->
*ESLint output is not relevant here, as we need to look into "Activity Monitor" instead.*

With the rule enabled, during the lint process (which we run as `eslint --ext .js,.vue .`) RAM consumption keeps raising and peaks at to 3.5G-4Gb level. When we disable the rule – it doesn't go more than 800-900Mb. I tried to disable other rules, and it seems this is the one which causes the issue.

I tried to debug it myself, and I narrowed it down to [this line](https://github.com/vuejs/eslint-plugin-vue/blob/master/lib/utils/style-variables/index.js#L35-L36):
```ts
/** @type {Map<VElement, StyleVariablesContext>} */
const cache = new Map()
```
This file is used in the [`style-css-vars-injection` syntax spec](https://github.com/vuejs/eslint-plugin-vue/blob/master/lib/rules/syntaxes/style-css-vars-injection.js#L7), which is part of the [`no-unsupported-features` rule](https://github.com/vuejs/eslint-plugin-vue/blob/master/lib/rules/no-unsupported-features.js#L28).
From my understanding, this `cache` is created globally per entire lint process, while it would be populated with values from each of the scanned files. This cache uses `VElement` objects as a key, which makes them "trapped" in this cache for the duration of the entire lint process. As a result Node.js cannot garbage collect those references when scan for individual file is done.

Simple change to `WeakMap` seems to be solving the problem:
```ts
/** @type {WeakMap<VElement, StyleVariablesContext>} */
const cache = new WeakMap()
```

Btw during my experiments, I noticed that [part of that code that reads from the `cache`](https://github.com/vuejs/eslint-plugin-vue/blob/master/lib/utils/style-variables/index.js#L55-L58) is **never executed**. I'm not sure what is the use case for this cache implementation, but for now it seems redundant for me and it could be removed altogether.

**Repository to reproduce this issue**
<!--
  ❗ Please share a repository that can reproduce your issue.
  ❗ If you don't share it, we just label it as requesting a repository that can reproduce your issue.
  ❗ If you don't share it for a few days, we silently close this issue.
-->
I'm not sure if you still need it, but I can add it if you confirm.
