568ad202 - Fix a long standing bug on file memory mapping on windows. (#25833)

Fix a long standing bug on file memory mapping on windows. (#25833) ### Description <!-- Describe your changes. --> While memory profiling some models I noticed multiple file mapping failures. `WindowsEnv::MapFileIntoMemory()` While it properly checks for the mapping offset to be granularity aligned, it calculates it as page aligned. Also, while saving external tensors we do not need to align big tensors to windows granularity or anything that is platform dependent. Set it to 4096 for all platforms. Granularity matters only for calculating mapping address. ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> Multiple failures for file mapping for certain models. This saves some hundreds of Mbs for some models.
