This patch adds JSON file for lrw core events, establishing a mapping mechanism between standard performance event names and hardware event codes. This allows users to specify monitoring events via semantic names (e.g., L1D_CACHE_REFILL) instead of traditional hardware encodings. Furthermore, this patch introduces metric definitions for the LRW RISC-V core in the vendor event JSON file. These metrics provide higher-level performance insights by aggregating and interpreting low-level hardware events, enabling semantic analysis through perf stat -M.
