Bug Fixes and Improvements

• #3526: Fix a potential NullPointerException in the macOS FFM process backend when an IOPlatformDevice entry has no readable name, and guard the native passwd/group struct dereferences against a null return - @dbwiddis.
• #3527: Consolidate the SLF4J log level dispatch duplicated in ExceptionUtil and PerfDataUtil into a new oshi.util.LogUtil, whose isEnabled method offers the slf4j 1.x-compatible equivalent of Logger#isEnabledForLevel - @dbwiddis.
• #3531: Stop reporting an implausible CPU or GPU temperature on Apple Silicon. An idle core cluster is power-gated and its die sensors then report a fixed parked value below room ambient, which was previously returned as a reading; Sensors#getCpuTemperature now reports 0 (unavailable) instead - @dbwiddis.
• #3535: Fix Sensors#getCpuTemperature returning 0 on Apple Silicon chips whose per-core SMC keys differ from the hardcoded set (e.g. the M3 Pro, where all five are absent). Prefer the chip-independent, firmware-computed CPU-die aggregate keys TCMb (die average) and TCMz (die max) before the per-core keys, reporting the die average - @dbwiddis.
• #3536: Discover Apple Silicon GPU temperature SMC keys at runtime instead of reading a fixed list of four chip-specific keys, and report the hottest GPU cluster rather than the first one found. Adds oshi.os.mac.sensors.gputemperature.keys to override the discovered keys - @dbwiddis.
• #3541: Identify Apple Silicon chips at runtime rather than from hardcoded tables that stopped at the M4. PhysicalProcessor#getEfficiency now classifies performance and efficiency cores from the IORegistry cluster-type property, fixing an all-zero classification (and the degraded per-core frequencies that followed from it) on newer chips, and ProcessorIdentifier#getMicroarchitecture falls back to a description derived from the core codenames instead of reporting unknown. An entry in oshi.architecture.properties still takes precedence where one exists - @dbwiddis.
• #3555: Fix Linux graphics cards all reporting the same VRAM, DRM device and GPU metrics: request the stable lspci -vnnmm machine-readable format so the Slot: field exists, stop discarding the PCI slot when entering a card record, and identify display controllers by PCI class 0x03 rather than a VGA substring match (expands to include XGA and others) - @Krillsson.
