In the same PMU, when some JSON events have the "BriefDescription" field
populated while others do not, the cmp_sevent() function will split these
two types of events into separate groups. As a result, when using perf
list to display events, the two types of events cannot be grouped together
in the output.

* Scale some metrics like dtlb_walk_ratio to percent so they display
better with Perf's 2 dp precision
* Description typos, grammar and clarifications
* Unnecessary metric formula brackets seem to have been removed in the
source but this is not a functional change
* New sve_all_percentage metric

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

Metrics will be published here [1] going forwards, but they have
slightly different scale units. To allow autogenerated metrics to be
added more easily, update the scale units to match.
The more detailed descriptions have also been taken and added to the
common file.

Generated from the telemetry solution repo[1] with this command:
./generate.py <linux-repo>/tools/perf/ --telemetry-files \
../../data/pmu/cpu/neoverse/neoverse-n1.json
Since this data source now includes the SPE events for N1, it has
diverged from A76 which means the folder has to be split.
The new data also uses more fine grained grouping, but this will be
consistent for all future products. Long PublicDescriptions are now
included even for common events because this can include product
specific details. For non verbose mode the common BriefDescriptions
remain the same.

Add general topdown L1 metrics for neoverse-n2-v2. Due to the wrong
count of stall_slot and stall_slot_frontend on neoverse-n2, the real
stall_slot and real stall_slot_frontend need to subtract cpu_cycles,
so overwrite the "MetricExpr" for neoverse-n2 which slots are 5.
Reference from ARM neoverse-n2 errata notice [0], D117.
Since neoverse-n2/neoverse-v2 does not yet support topdown L2, metric
groups such as Cache, TLB, Branch, InstructionsMix and PEutilization
will be added to further analysis of performance bottlenecks in the
following patches. Reference from ARM PMU guide [1][2].

The metrics of topdown L1 are from ARM sbsa7.0 platform design doc[0],
D37-38, which are standard. So put them in the common file sbsa.json of
arm64, so that other cores besides n2/v2 can also be reused.
