Morph 99ceb03a1c general: Convert source file copyright comments over to SPDX 
This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

Morph 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.

HW.Memory <Critical> common/host_memory.cpp:HostMemory:492: Fastmem unavailable, falling back to VirtualBuffer for memory allocation

lat9nq 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.

Markus Wick 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.

Markus Wick 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.
