AG-16239: Add high-frequency data benchmarks for bar, candlestick, OHLC, and line series

[alantreadway]

This PR adds comprehensive benchmarks for high-frequency data scenarios across multiple chart series types.

Changes

• Added high-frequency data benchmarks for bar series (community)
• Added high-frequency data benchmarks for candlestick series (enterprise)
• Added high-frequency data benchmarks for OHLC series (enterprise)
• Updated high-frequency data benchmarks for line series (community)
• Added corresponding example files for all benchmark types
• Updated project.json configurations for benchmark example generation

Reviewers

This PR should be reviewed by the Charts dev team as it focuses on benchmark additions and library functionality.

Reset repeat count before single-run benchmarks

After calling ctx.repeatCount(10) for the "10x append batch" test, the same BenchmarkContext is reused for the subsequent "1x remove" and "1x rolling window" cases without resetting repeat. repeatCount mutates the context and the benchmark helper reads ctx.repeat directly, so both "1x" tests are actually executed ten times each. That inflates timings and memory measurements and risks timeouts. Reset the repeat count (e.g. ctx.repeatCount(1)) before the single-run benchmarks, and apply the same fix to the bar/candlestick/ohlc high-frequency tests which follow the same pattern.

Reset repeat count before single-run benchmarks

Fixed.
