Implement support for page sizes > 4KB (#4252)1.1.568
* Implement support for page sizes > 4KB
* Check and work around more alignment issues
* Was not meant to change this
* Use MemoryBlock.GetPageSize() value for signal handler code
* Do not take the path for private allocations if host supports 4KB pages
* Add Flags attribute on MemoryMapFlags
* Fix dirty region size with 16kb pages
Would accidentally report a size that was too high (generally 16k instead of 4k, uploading 4x as much data)
