Add reusable memory-map helpers to collect Linux memory artifacts without Android-only tools such as procrank or dmabuf_dump. The helpers collect /proc, /sys, debugfs, DMA-BUF, KGSL, zram, slab, vmalloc, reserved-memory, per-process smaps_rollup and platform details. They also generate a final stdout-friendly memory component summary using Qualcomm-style formulas for NHLOS, Kernel Static, Apps + Framework and Free Memory.

Add the Memory_Map performance test to collect memory-map and memory debug artifacts on Yocto targets. The test supports configurable output directory, collection delay, top process count, debugfs mounting and verbose debug output. It prints a final memory component table to stdout for quick triage and documents the collected artifacts, formulas, usage examples and LAVA parameters.

Add a new
Memory_Mapperformance test for Yocto targets and extend[lib_performance.sh](http://lib_performance.sh/)with reusable memory collection helpers.This test replaces the older dependency on Android-only tools such as
procrankanddmabuf_dumpby collecting equivalent debug data from standard Linux interfaces such as/proc,/sys, debugfs, DMA-BUF, KGSL, zram, slab, vmalloc and per-processsmaps_rollup.The summary follows Qualcomm-style memory accounting:
NHLOS = rounded total RAM - Total Linux memoryKernel Static = Total Linux memory - MemTotalApps + Framework = sum of process PSS from /proc/*/smaps_rollupFree Mem = MemAvailable
