RFC LinuxCNC#3286 narrow option 1: fix float position wrap on high-count encoders via 64-bit internal counters, without exposing new HAL pin types. s32 count/rawcounts/rawlatch/ count-latched remain as truncated views of the internal 64-bit counters. Float position is computed from the full 64-bit value so it does not wrap. Avoids committing four integer pin types (s32/u32/s64/u64) into 2.10 ABI before the getter/setter direction in LinuxCNC#3286 is decided. The overflow fix from 8a3ac3f is preserved; only the pin exposure is reverted. Unused prev_event_rawcounts_64 dropped. BREAKING CHANGE: count_64, rawcounts_64, rawlatch_64 and count-latched_64 pins added post-2.9 are removed. HAL surface matches 2.9. Refs LinuxCNC#3286 LinuxCNC#2331
