perf stat: Setup the foundation to allow aggregation based on cache topology
Processors based on chiplet architecture, such as AMD EPYC and Hygon do not expose the chiplet details in the sysfs CPU topology information. However, this information can be derived from the per CPU cache level information from the sysfs.
'perf stat' has already supported aggregation based on topology information using core ID, socket ID, etc. It'll be useful to aggregate based on the cache topology to detect problems like imbalance and cache-to-cache sharing at various cache levels.
This patch lays the foundation for aggregating data in 'perf stat' based on the processor's cache topology. The cmdline option to aggregate data based on the cache topology is added in Patch 4 of the series while this patch sets up all the necessary functions and variables required to support the new aggregation option.
The patch also adds support to display per-cache aggregation, or save it as a JSON or CSV, as splitting it into a separate patch would break builds when compiling with "-Werror=switch-enum" where the compiler will complain about the lack of handling for the AGGR_CACHE case in the output functions.
Committer notes:
Don't use perf_stat_config in tools/perf/util/cpumap.c, this would make code that is in util/, thus not really specific to a single builtin, use a specific builtin config structure.
Move the functions introduced in this patch from tools/perf/util/cpumap.c since it needs access to builtin specific and is not strictly needed to live in the util/ directory.
With this 'perf test python' is back building.

perf cpumap: Fix alignment for masks in event encoding
A mask encoding of a cpu map is laid out as:

perf cpumap: Fix alignment for masks in event encoding
A mask encoding of a cpu map is laid out as:
u16 nr u16 long_size unsigned long mask[];
However, the mask may be 8-byte aligned meaning there is a 4-byte pad after long_size. This means 32-bit and 64-bit builds see the mask as being at different offsets. On top of this the structure is in the byte data[] encoded as:
u16 type char data[]
This means the mask's struct isn't the required 4 or 8 byte aligned, but is offset by 2. Consequently the long reads and writes are causing undefined behavior as the alignment is broken.
Fix the mask struct by creating explicit 32 and 64-bit variants, use a union to avoid data[] and casts; the struct must be packed so the layout matches the existing perf.data layout. Taking an address of a member of a packed struct breaks alignment so pass the packed perf_record_cpu_map_data to functions, so they can access variables with the right alignment.
As the 64-bit version has 4 bytes of padding, optimizing writing to only write the 32-bit version.
Committer notes:
Disable warnings about 'packed' that break the build in some arches like riscv64, but just around that specific struct.

perf cpumap: Give CPUs their own type
A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t.
Committer notes:
To make it build with BUILD_BPF_SKEL=1 these files needed the conversions to 'struct perf_cpu' usage:
tools/perf/util/bpf_counter.c tools/perf/util/bpf_counter_cgroup.c tools/perf/util/bpf_ftrace.c
Also perf_env__get_cpu() was removed back in "perf cpumap: Switch cpu_map__build_map to cpu function".
Additionally these needed to be fixed for the ARM builds to complete:
tools/perf/arch/arm/util/cs-etm.c tools/perf/arch/arm64/util/pmu.c

perf cpumap: Add CPU to aggr_cpu_id
With no aggregration, such as 'perf stat -A', the aggr_cpu_id lacks a way to describe per CPU aggregation and the core is set to the CPU in places like print_counter_aggrdata in stat-display.c.
Setting the core to the CPU is undesirable as the CPU will exceed valid core values and lead to confusion. Add a CPU variable to address this.
