Description
### Is your feature request related to a problem or challenge?
Hi, I'm trying to reduce the size of my compiled binary. Using cargo bloat, it appears that a large portion of the size (around 10%) is coming from the dependency on the brotli compression algorithm. I don't plan on compressing or decompressing anything using brotli, so I'd like to disable this dependency. Ideally, I would only depend on zstd, since that is the only algorithm I plan to use.
Currently, I have `default-features = false` and `features = ["parquet"]`. This is enough to pull in all of the compression algorithms, since the parquet has default features enabled.
I'm less familiar with Rust build systems, so my analysis of the situation might be incorrect.
### Describe the solution you'd like
Could we do something similar to #10058, where top level features are exposed by the datafusion crate, and this toggles on or off the features inside the parquet crate?

Research direction
Start by tracing the Cargo feature declarations for DataFusion and its parquet dependency, using cargo tree to inspect which compression features are enabled. Done means parquet remains available while brotli can be disabled and zstd can remain enabled, with the resulting dependency graph confirming the unused algorithm is absent.
