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. https://github.com/uxlfoundation/oneTBB/blob/280e32f8871699d3c107e77a8731b612b0eccd3b/test/tbbmalloc/test_malloc_whitebox.cpp#L1263 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 https://github.com/uxlfoundation/oneTBB/issues/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.
