ZipArchive: Improve performance or removing extra fields

This improves the performance of the `ZipArchive` by optimizing the removal of extra fields.
- `src/libraries/System.IO.Compression/src/System/IO/Compression/ZipBlocks.cs`: Replaced multiple iterations and list operations with a single `RemoveAll` call to remove specific `ZipGenericExtraField` entries.
