Add tool PMU events to report memory usage information exposed by
/proc/pid/smaps_rollup and /proc/pid/statm.
The following events are added:
- memory_anon_huge_pages
- memory_anonymous
- memory_data
- memory_file_pmd_mapped
- memory_ksm
- memory_lazyfree
- memory_locked
- memory_private_clean
- memory_private_dirty
- memory_private_hugetlb
- memory_pss
- memory_pss_anon
- memory_pss_dirty
- memory_pss_file
- memory_pss_shmem
- memory_referenced
- memory_resident
- memory_rss
- memory_shared
- memory_shared_clean
- memory_shared_dirty
- memory_shared_hugetlb
- memory_shmem_pmd_mapped
- memory_size
- memory_swap
- memory_swap_pss
- memory_text
- memory_uss
The events are aggregated across processes in system-wide mode, or
reported per-process when monitoring specific tasks. The tool_pmu
implementation is updated to read from /proc files and tool.json is
updated with the new events and detailed descriptions. The data can
only be gathered for a running process except for memory_rss and
memory_resident that use rusage data from wait4 to give a final value.
Examples of gathering system-wide statm and smaps_rollup based events:
```
