Acknowledge TASTY as known ClassFile attribute in ijar

Currently producing `ijar` using Scala 3 produces the following warnings:
```
ijar: skipping unknown attribute: "TASTY".
```

TASTY is a Scala 3 specific ClassFile attribute and informs that for given `.class` file there is also emmited as `.tasty` file (these were handled in #12529). It can be consumed in the same way as currently handled `Scala` and `ScalaSig` attributes.
Handling that should remove redundant warnings

Here's example on how this attribute is emmited:
https://github.com/scala/scala3/blob/91ef92159c628eaeab8311dc82bed7ed4fe03c63/compiler/src/dotty/tools/backend/jvm/CodeGen.scala#L92-L110

Closes #24165.
