This patch adds micro-benchmarks for TypedArray#join with and without a separator.
The benchmark can be used to measure any TypedArray#join optimizations we implement in the future.

Test:

  tools/run_perf.py --binary-override-path=out/x64.release/d8 \
    --filter JSTests/TypedArrays/Join \
    test/js-perf-test/JSTests.json

'ref' builds might not yet have BigInt support. Instead of crashing
when the benchmark file is loaded, the benchmark now fails during
setup.

This CL adds sort benchmarks for BigUint64Array and BigInt64Array.
They form their own benchmark group separate from the Int and
Float types/element kinds.

Benchmark now sorts every element type of TypedArray and groups the
benchmarks by integer and floating point types. Also adding a sort

This constructs different typed arrays from different types of other
typed arrays, hopefully countering microbenchmarks which are able to
optimize for exactly one pair of types.

This should be the fastest case, as we can just copy the backing store
directly. Adding this test so that we can monitor if upcoming changes
regress this path.

Add a simple benchmark for a TypedArray constructor. Run once with the
default pipeline and once with turbofan so that we can compare the
performance.

Also fixes a typo in the Regex for the result of the CopyWithin

dashboard.
