[dpdk-dev] [PATCH 1/2] test/meson: hash test split into shorter subtests

From: Amit Gupta <agupta3 at marvell.com>

hash_readwrite meson test was taking longer time to complete.
The test always get TIMEOUT, hence test is split into
functional and perf test. perf test is being moved under
dpdk perf testsuites in  meson build.
