Whitebox tests hardcode huge page size as 2M, causing failures when system huge page size differs (e.g., 512M)

[guodashun]

When running TBB whitebox tests, some test cases (e.g., those related to huge page memory) hardcode the huge page size as 2MB. If the system is configured with a non-2MB huge page size (e.g., 512MB or other sizes), the test assertions fail, reducing the adaptability of the test suite across environments.

oneTBB/test/tbbmalloc/test_malloc_whitebox.cpp

Line 1263 in 280e32f

const int HUGE_PAGE_SIZE = 2 * 1024 * 1024;

In my env, the config is:

Hugepagesize:       524288 kB
Hugetlb:               0 kB

so I got the error is:

/home/xxxxx/test/tbbmalloc/test_malloc_whitebox.cpp:xxx: FATAL ERROR: REQUIRE( allocSize == HUGE_PAGE_SIZE ) is NOT correct!
  values: REQUIRE( 536870912 == 2097152 )
  logged: Allocation size have to be aligned on Huge Page size internally.

like this issue #677

This issue may affect CI/CD pipelines or cloud environments where non-2MB huge pages are common. If further debugging data or testing assistance is needed, feel free to request.
