GH-32240: [C#] Add new Apache.Arrow.Compression package to implement IPC decompression (#33893)

### Rationale for this change

This further addresses #32240 and is a follow up to PR #33603 to provide an implementation of the `ICompressionCodecFactory` interface in a new `Apache.Arrow.Compression` package. Making this a separate package means users who don't need IPC decompression support don't need to pull in extra dependencies.

### What changes are included in this PR?

Adds a new `Apache.Arrow.Compression` package and moves the existing compression codec implementations used for testing into this package.

### Are these changes tested?

There are unit tests verifying the decompression support, but this also affects the release scripts and I'm not sure how to fully test these.

### Are there any user-facing changes?

Yes, this adds a new package users can install for IPC decompression support, so documentation has been updated.
* Closes: #32240
