[WPERF-600] Add PARSE_INTERVAL_DEFAULT constant as pmu_device.sampling.INTERVAL_DEFAULT to `wperf test`

Introduction

Default sampling frequency is defined in wperf like this:

windowsperf/wperf$ git grep PARSE_INTERVAL_DEFAULT
parsers.cpp:        uint32_t interval = PARSE_INTERVAL_DEFAULT;
parsers.h:inline constexpr uint32_t PARSE_INTERVAL_DEFAULT = 0x4000000;

We want to show this value in wperf test output so tools like vs-extension can use it in GUI/UX workflow. Example output from wperf test after this change:

>wperf test

In this patch:

• wperf-scripts: add test for 'pmu_device.sampling.INTERVAL_DEFAULT'
• wperf: add parser::PARSE_INTERVAL_DEFAULT as pmu_device.sampling.INTERVAL_DEFAULT

This is default sampling frequency when users do not specify frequency with command line.
