BaseTools: Remove /Oi from Visual Studio tool chains.

BaseTools: Remove /Oi from Visual Studio tool chains.

Remove /Oi from Visual Studio tool chains. because of the following reasons:
1. Intrinsic is Compiler-dependent.
2. Adding /Oi (Generate Intrinsic Functions) doesn't promise 100% replacing
   the function call with inline functions.
   /Oi is only a request, but doesn't force, the compilers to use the intrinsic.
   The visual studio optimizer can still use the library version.
3. Since EDK2 doesn't include Visual Studio header files, intrinsic function
   should not be used.

Built Nt32Pkg, OvmfPkg, ShellPkg, MdeModulePkg and CryptoPkg successfully.
