test(wasmtest): enable compression feature for wasm build

[ChanTsune]

Which issue does this PR close?

• Refs Switch from xz2 to liblzma to reduce duplicate dependencies #17509 (Switch from xz2 to liblzma to reduce duplicate dependencies)

Rationale for this change

Switching from xz2 to liblzma enabled wasm builds (liblzma supports wasm),
so we can now enable the compression feature in wasm tests.

What changes are included in this PR?

• Add the compression feature to the datafusion dependency in datafusion/wasmtest/Cargo.toml.

Are these changes tested?

• Verified by CI in this PR.

Are there any user-facing changes?

• No. (test configuration change only)

Do the existing tests in wasmtest utilize the compression feature or would we need to add a new one?

[ChanTsune]

The existing wasm tests do not use the compression feature.
I have verified that the crate can be compiled for the wasm target.
If tests that exercise the compression feature are required, I will add them in this PR.

It would be good to add a test
