[common/core/dynarmic] Optimize page table allocations (#4219)

2026-09-09T19:35:49+00:00

Reduces the page entries from 32 bytes to 8 and rewrites `VirtualBuffer` to be more efficient in memory usage and specifically for large zero regions. The page table will now only reserve 1GiB instead of 4GiB and of this memory it should only use at most ~8MiB. This PR has the side effect of using Eden on Windows on low memory systems much more plausible since it would previously require ~10GiB of committable memory at front (despite using ~5-6 at most, inadvertently stalling other processes) where as now it should only require around the amount that it'll actually use.

page_table: Allow page tables to be moved

2020-11-18T01:08:20+00:00

Makes page tables and virtual buffers able to be moved, but not copied, making the interface more flexible. Previously, with the destructor specified, but no move assignment or constructor specified, they wouldn't be implicitly generated.
