On Windows, expanding the stack by more than 4 KB at a time can cause access violations. This change fixes a few known cases (and includes unit tests for those), and attempts to make stack expansion more consistent overall by using the AllocateStackSpace helper method everywhere we can, even when the offset is a small constant. On arm64, there was already a consistent method for stack pointer manipulation using the Claim and Drop methods, so Claim is updated to touch every page.
