[msmpi] Fix /MD for static libs.

[NancyLi1013]

When building static library with dynamic CRT, it failed with:

Expected Release,Dynamic crt linkage, but the following libs had invalid crt linkage:

    F:/vcpkgissue/vcpkg/packages/msmpi_x64-windows/lib/msmpifec.lib: Release,Static
    F:/vcpkgissue/vcpkg/packages/msmpi_x64-windows/lib/msmpifmc.lib: Release,Static

To inspect the lib files, use:
    dumpbin.exe /directives mylibfile.lib

So I added set(VCPKG_CRT_LINKAGE static) to fix it.

This is (unfortunately) not a bug.

CRT linkage MUST be the same between the consumer and the library (except very, very special libraries).

In this case, the consumer's code will be using the dynamic CRT. Therefore, we must also ensure that any libraries we install are also using the dynamic CRT.

Looking at what we have available, I've changed the install process to not install those particular libraries when building against the static crt. I think this should fix the user's issue.

@ras0219-msft, thanks a lot for your clear description and your efforts for this PR. I have gotten it. I'll pay more attention to these types of issues.
