Replace closed WDFCVBI2.COD with from-scratch open SD/FAT32 driver

Browse Source

Renamed as zc_sd_driver.asm/zc_sd_driver_body.asm (no relation to Wild
Commander). Fixes a stale-IX bug where core_mkfile's filter_name_to_83
left IX pointing into driver memory instead of restoring it, causing
zifi.asm's save_downloaded_file to read the wrong page/address for
every SAVE512 call after MKFILE. All CORE dispatch entry points now
preserve IX across the call. Also fixes a body/#2000 jump-table
overlap, sdbuf DMA word-alignment, and a load_ram_page staleness race
in zifi.asm's own download bookkeeping.
