cleanup CPU model & feature detection 
Add std.Target.Cpu.Model.generic which is even more empty than baseline.
CPU model and feature detection uses this rather than baseline.

Rename cpu_detected to cpu_detection_unimplemented and flip the logic.
It can be relied on by stage2.zig to decide whether the LLVM workaround
is needed without also checking the CrossTarget.

Move the CPU detection to after the OS detection, and use the detected
OS for the CPU detection. This is relevant because operating systems
sometimes emulate certain CPU features, so knowing the OS and version is
relevant for determining CPU features.

Prepare for #4592 by passing the CPU arch to the detection code, instead
of having it rely on Target.current.

The CPU model & feature detection logic is modified. Before:

 * Detect actual features
 * Use as hint when detecting CPU model
 * Populate dependencies of CPU model features
 * Merge that into the actual features set

After:

 * Detect actual features
 * Use as hint when detecting CPU model
 * Add known CPU model features to actual features
 * Detect actual features again, overriding known CPU model features
 * Populate dependencies

stage1: make get_optional_type more robust 
Now it will emit a compile error rather than crashing when the child
type has not been resolved properly.

Introduces `get_optional_type2` which should be used generally inside
ir.cpp.

Fix some std lib compile errors noticed by the provided test case.

Thanks @LemonBoy for the test case. Closes #4377.

Fixes #4374.

2e04b61275 std: Work around unexported NtCurrentTeb 
Apparently NtCurrentTeb is only exported for i386 and some other
platforms but not for x86_64 nor AArch64. Let's go with the flow and
provide our own NtCurrentTeb like the Windows headers do.

Thank you Microsoft.

Use the NtCurrentTeb API instead of using some inline asm, this is much
nicer and also more portable.
