The JSON Unit field encodes the name of the PMU to match the events
to. When no name is given it has meant the "cpu" core PMU except for
tests.
On ARM, Intel hybrid and s390 the core PMU is named differently which
means that using "cpu" for this case causes the events not to get
matched to the PMU.
Introduce a new "default_core" string for this case and in the
pmu__name_match force all core PMUs to match this name.

Unit with the PMU name is appended to desc in jevents.py, but on
hybrid platforms it causes the desc to differ from the regular
non-hybrid system with a PMU of 'cpu'. Having differing descs means
the events don't deduplicate. To make the perf list output not differ,
append the Unit on again in the perf list printing code.
On x86 reduces the binary size by 409,600 bytes or about 4%. Update
pmu-events test expectations to match the differently generated
pmu-events.c code.

Prior to this change a cpuid would map to a list of events where the PMU
would be encoded alongside the event information. This change breaks
apart each group of events so that there is a group per PMU. A new table
is added with the PMU's name and the list of events, the original table
now holding an array of these per PMU tables.
These changes are to make it easier to get per PMU information about
events, rather than the current approach of scanning all events. The
perf binary size with BPF skeletons on x86 is reduced by about 1%. The
unidentified PMU is now always expanded to "cpu".

Recently Ilkka reported that the JSONs for the AmpereOne arm64-based
platform included a dud event which referenced a non-existent arch std
event [0].
Previously in the times of jevents.c, we would raise an exception for this.
This is still invalid, even though the current code just ignores such an
event.
Re-introduce code to raise an exception for when no definition exists to
help catch as many invalid JSONs as possible.

Apart from some slight naming and grouping differences, the new metrics
are functionally the same as the existing ones. Any missing metrics were
manually appended to the end of the auto generated file.
For the events, the new data includes descriptions that may have product
specific details and new groupings that will be consistent with other
products.
After generating the metrics from the telemetry repo [1], the following
manual steps were performed:
* Change the topdown expressions to compare on CPUID and use
#slots so that the same data can be shared between N2 and V2. Apart
from these modifications, the expressions now match more closely with
the Arm telemetry data which will hopefully make future updates
easier.
* Append some metrics from the old N2/V2 data that aren't present in
the telemetry data. These will possibly be added to the
telemetry-solution repo at a later time:
l3d_cache_mpki, l3d_cache_miss_rate, branch_pki, ipc_rate, spec_ipc,
retired_rate, wasted_rate, branch_immed_spec_rate,
branch_return_spec_rate, branch_indirect_spec_rate

N2 r0p3 doesn't require the workaround [1], so gating on (#slots - 5) no
longer works because all N2s have 5 slots. Use the new expression
builtin that allows calling strcmp_cpuid_str() and comparing CPUIDs in
metric formulas.
In this case, the commented formula looks like this:
strcmp_cpuid_str(0x410fd493) # greater than or equal to N2 r0p3
| strcmp_cpuid_str(0x410fd490) ^ 1 # OR NOT any version of N2

This will allow writing formulas that are conditional on a specific
CPU type or CPU version. It calls through to the existing
strcmp_cpuid_str() function in Perf which has a default weak version,
and an arch specific version for x86 and arm64.
The function takes an 'ID' type value, which is a string. But in this
case Arm CPU IDs are hex numbers prefixed with '0x'. metric.py
assumes strings are only used by event names, and that they can't start
with a number ('0'), so an additional change has to be made to the
regex to convert hex numbers back to 'ID' types.

The flex and bison generate header files from the source. When user
specified a build directory with O= option, it'd generate files under
the directory. The build command has -I option to specify the header
include directory.
But the -I option only affects the files included like <...>. Let's
change the flex and bison headers to use it instead of "...".

The bison and flex generate C files from the source (.y and .l)
files. When O= option is used, they are saved in a separate directory
but the default build rule assumes the .C files are in the source
directory. So it might read invalid file if there are generated files
from an old version. The same is true for the pmu-events files.
For example, the following command would cause a build failure:
$ git checkout v6.3
$ make -C tools/perf # build in the same directory
$ git checkout v6.5-rc2
$ mkdir build # create a build directory
$ make -C tools/perf O=build # build in a different directory but it
# refers files in the source directory
Let's update the build rule to specify those cases explicitly to depend
on the files in the output directory.
Note that it's not a complete fix and it needs the next patch for the
include path too.

There are cases where a metric requires more events than the number of
available counters. E.g. AMD Zen, Zen 2 and Zen 3 processors have four
data fabric counters but the "nps1_die_to_dram" metric has eight events.
By default, the constituent events are placed in a group and since the
events cannot be scheduled at the same time, the metric is not computed.
The "all metrics" test also fails because of this.
Use the NO_GROUP_EVENTS constraint for such metrics which anyway expect
the user to run perf with "--metric-no-group".
E.g.
$ sudo perf test -v 101
Before:
101: perf all metrics test :
--- start ---
test child forked, pid 37131
Testing branch_misprediction_ratio
Testing all_remote_links_outbound
