Add Zstd.isAvailable() check in ZstdOptions (#11597) 

Motivation:

At present, the verification methods of `ZstdOptions` and `BrotliOptions` are not consistent, and the processing methods of `ZstdOptions` and `BrotliOptions` in `HttpContentCompressor` are also inconsistent.
The http2 module does not add zstd-jni dependency, so `ClassNotFoundException` may be thrown

Modification:

Added `Zstd.isAvailable()` check in `ZstdOptions` to be consistent, and added zstd-jni dependency in http2 module

Result:

The verification methods of `ZstdOptions` and `BrotliOptions` are consistent, and `ClassNotFoundException` will not be thrown
