compressor: use a prevector in compressed script serialization

Use a prevector for stack allocation instead of heap allocation during
script compression and decompression. These functions were doing
millions of unnecessary heap allocations during IBD.

We introduce a CompressedScript type alias for this prevector. It is
size 33 as that is the maximum size of a compressed script.

Fix the DecompressScript header to match the variable name from
compressor.cpp
