[SYCL] Fix mismatched-new-delete warning in compression.hpp

[uditagarwal97]

Fixed the following warning when DPC++ is built in Release mode with gcc 13:

In member function 'void std::default_delete<_Tp>::operator()(_Tp*) const [with _Tp = char]',
    inlined from 'std::unique_ptr<_Tp, _Dp>::~unique_ptr() [with _Tp = char; _Dp = std::default_delete<char>]' at /usr/include/c++/13/bits/unique_ptr.h:404:17,
    inlined from 'static std::unique_ptr<char> sycl::_V1::detail::ZSTDCompressor::DecompressBlob(const char*, size_t, size_t&)' at /tmp/llvm/sycl/source/detail/compression.hpp:139:3,
