Fix licensing issues in source release found during 0.63.0 RC1 vote (missing NOTICE file, flamegraph.svg with CDDL-licensed JavaScript)

**Describe the bug**

During the vote on the Apache DataFusion sqlparser-rs `0.63.0` RC1 release, @Xuanwo identified two licensing-material issues in the source archive and voted -1 (non-binding): https://lists.apache.org/thread/3lnhgs0bwzl148yrdrcl5g005h9pgtmx

1. **Missing `NOTICE` file**: the source archive contains `LICENSE.TXT` but no `NOTICE` file, which ASF releases are expected to include.
2. **`sqlparser_bench/img/flamegraph.svg` embeds third-party licensed code**: the generated flamegraph embeds JavaScript from [Inferno](https://github.com/jonhoo/inferno), whose upstream license is CDDL 1.0, but the archive contains no corresponding license materials.

**To Reproduce**

Download and unpack the 0.63.0 RC1 source archive (or check the repository at `v0.63.0-rc1`):

```shell
$ ls NOTICE*
ls: NOTICE*: No such file or directory

$ grep -c -i inferno sqlparser_bench/img/flamegraph.svg
2
```

**Expected behavior**

The source release complies with ASF licensing policy:

1. Add a `NOTICE` file to the repository so it is included in source archives.
2. Exclude the generated `sqlparser_bench/img/flamegraph.svg` from the source release

**Additional context**

从 repository 根目录开始，使用 0.63.0-rc1 源代码归档并检查 NOTICE、LICENSE.TXT 和 sqlparser_bench/img/flamegraph.svg；运行 issue 中的 ls 和 grep 检查以确认发现。完成的标准是源代码发行版包含所需的 NOTICE 文件，并排除生成的 flamegraph.svg，同时不保留采用 CDDL 许可的 JavaScript。
