[PATCH] perf vendor events arm64: Fix typos in event descriptions

[PATCH] perf vendor events arm64: Fix typos in event descriptions

[TAKANO Mitsuhiro]

Six entries in common-and-microarch.json spell Statistical as "Statisical"
(the SAMPLE_FEED_* events), and one entry in the Fujitsu a64fx table, the
L2HWPF_STREAM_PF event, spells prefetcher as "prefecher" in both its
BriefDescription and its PublicDescription.

The SAMPLE_FEED_* events are inherited through ArchStdEvent by the
neoverse-n3, neoverse-v3 and t410 tables, so the misspelling reaches those
three generated tables.  The a64fx pair appears once, because the long
description is dropped when it equals the brief one.

Spell the words correctly.  Event names, codes and expressions are
unchanged.

Written with Hermes Agent, an LLM assistant.  Running jevents.py for arm64
before and after this change removes 12 occurrences of "Statisical" and the
one "prefecher" from the generated string table; perf was not rebuilt.

Fixes: 994256a79867 ("perf vendor events arm64: Add N3 events/metrics")
Fixes: 5497b23e870c ("perf vendor events arm64: Add Fujitsu A64FX pmu event")
