requiredAllocSize in min_max_mem_alloc_size does not match current CL_DEVICE_MAX_MEM_ALLOC_SIZE minimum for either profile

Related to #2795

min_max_mem_alloc_size in test_conformance/api/test_api_min_max.cpp hardcodes:

    if (gIsEmbedded)
        requiredAllocSize = 1 * 1024 * 1024;
    else
        requiredAllocSize = 128 * 1024 * 1024;

Current spec text for CL_DEVICE_MAX_MEM_ALLOC_SIZE:

Max size of memory object allocation in bytes. The minimum value is max(min(1024 x 1024 x 1024, 1/4th of CL_DEVICE_GLOBAL_MEM_SIZE), 32 x 1024 x 1024).

That puts the actual floor at 32 MB for full profile, not 128 MB.

CL_DEVICE_MAX_MEM_ALLOC_SIZE has no entry in the embedded profile relaxation table (embedded-device-queries-table in embedded_profile.asciidoc), so the same 32 MB floor applies to embedded devices too. The 1 MB used here is roughly 32x below that.

Questions:

• Should requiredAllocSize be lowered to 32 MB for both profiles to match the documented minimum, or is there a reason CTS intentionally holds a stricter bar for full profile and a laxer one for embedded?
• If the latter, should the spec wording be revisited instead?
