[SYCL] Do not link `zstd` to SYCL RT directly, use LLVMSupport instead

Is your feature request related to a problem? Please describe

Now that we link LLVMSupport library to SYCL RT (#16763), we can use llvm/Support/Compression.h(https://llvm.org/doxygen/Compression_8h.html) for zstd decompression and we can altogether avoid linking zstd to SYCL RT.

Currently, blocked on llvm/llvm-project#107020 - we need to have an API in LLVMSupport to get decompressed image size without having to actually decompress. ZSTD provides such an API, but LLVMSupport currently doesn't.
