xz: Ignore filter chains that are set but never used in --block-list.
If a filter chain is set but not used in --block-list, it introduced unexpected behavior such as requiring an unneeded amount of memory to compress, reducing the number of threads in multi-threaded encoding, and printing an incorrect amount of memory needed to decompress. This also renames filters_init_mask => filters_used_mask. A filter is assumed to be used if it is specified in --filtersX until coder_set_compression_settings() determines which filters are referenced in --block-list.
