Espressif benchmark update

[gojimmypi]

Description

This PR Updates the wolfcrypt benchmark.c to take into account various issues for different Espressif SoC devices.

This is a companion PR to #7035 and all of the following are now supported:

• esp32
• esp32c2
• esp32c3
• esp32c6
• esp32s2
• esp32s3
• esp32h2

A new DEBUG_WOLFSSL_BENCHMARK_TIMING macro is introduced to enable verbose timing related debugging.

A new MILLION_VALUE macro is introduced for the fixed value of 1,000,000.0 (1000000.0)

As the CPU Cycle Counter is known to overflow during benchmarks on slower, embedded systems, a new multi-overflow implementation now calculated approximate CPU cycle counts when needed using the FreeRTOS tick counts, instead. As the TickCounts are not guaranteed to start at the "beginning of time" for RTOS, we lose some granularity, depending on configTICK_RATE_HZ.

• Edit: Not included in this PR are sample benchmarks from various configurations. Please see the examples in my dev fork.

See #6234 for a roadmap of Espressif updates.
