584e8b5c52 host_memory: merge adjacent placeholder mappings on Linux
Track the private anonymous placeholder mappings created by Unmap() and
wherever possible, replace existing placeholders with larger ones
instead of creating many small ones.

This helps with the buildup of mappings in /proc/YUZU_PID/maps after a
longer gaming session, improving stability without having to increase
vm.max_map_count to a ridiculous value. The amount of placeholder
mappings will no longer outgrow the amount of actual memfd mappings in
cases of high memory fragmentation.

b33f23cc46 host_memory: Fix fastmem crashes in debug builds
It is possible for virtual_offset to not be 0 when the iterator is at the beginning, and thus, std::prev(it) may be evaluated, leading to a crash in debug mode.

9a06b85b24 host_memory: Correct MEM_RESERVE_PLACEHOLDER
Microsoft defines `MEM_RESERVE_PLACEHOLDER` as `0x00040000`, but our
manually imported version of it drops the last zero.

7f85abb281 common/host_memory: Implement a fallback if fastmem fails.
This falls back to the old approach of using a virtual buffer.

Windows is untested, but this build should fix support for Windows < 10 v1803. However without fastmem support at all.

c4609c92ee common/host_memory: Optimize for huge tables.
In theory, if we have 2 MB continously mapped, this should save one layer of TLB.
Let's make it at least more likely by aligning the memory.
