HOST_APPLICATION limitation

Zhiguang and Ray:
Thanks for your sharing. It is OK to use UnitTestHostBaseLib in emulator
platform.
Please also update the file header in module inf to describe this usage.

Thanks
Liming

HOST_APPLICATION limitation

Hi Liming,
Like ray said, we are trying to use some baselib function in
EmulatorPkg, which is assembly code in normal BaseLib, and is mocked
in UnitTestBaseLib, such as AsmWriteMsr64 and AsmCpuid.

Thanks
Zhiguang

HOST_APPLICATION limitation

Liming,
We are running some code that requires MSR access (e.g.: MtrrLib) in
EmulatorPkg.

Thanks,
Ray

Can you explain more about the emulator usage model for this library?

Remove HOST_APPLICATION limitation for UnitTestHostBaseLib, so
that this library can be used as BaseLib by Emulator.
Also, add some missing files
