Enable LARGEADDRESSAWARE for 32 bit compilation (KhronosGroup#1858)

* Enable LARGEADDRESSAWARE for 32 bit compilation 32-bit executables built with MSVC linker have only 2GB virtual memory address space by default, which might not be sufficient for some tests. Enable LARGEADDRESSAWARE linker flag for 32-bit targets to allow tests to handle addresses larger than 2 gigabytes. https://learn.microsoft.com/en-us/cpp/build/reference/largeaddressaware-handle-large-addresses?view=msvc-170 Signed-off-by: Guo, Yilong <[email protected]> * Apply suggestion Co-authored-by: Ben Ashbaugh <[email protected]> --------- Signed-off-by: Guo, Yilong <[email protected]> Co-authored-by: Ben Ashbaugh <[email protected]>
