```
windows: replace GetPhysicallyInstalledSystemMemory with ntdll.

`GetPhysicallyInstalledSystemMemory` uses SMBios to grab the physical
memory size which can lead to unecessary allocation and inacurate
representation of the total memory. Using `System_Basic_Information`
help to retrieve the physical memory which is not reserved for the
kernel/tables. This aligns better with the linux side as `/proc/meminfo`
does the same thing.

```
