cmake: Avoid leaking absolute paths into exported config

The `find_libarary` command resolves the library or framework
into an absolute path. In case of system frameworks which are
located within an Xcode-provided SDK this results in the Xcode
path and SDK version being part of the library path.

Because those library paths end up in the exported CMake config
importing curl will fail once the Xcode location or SDK version
changes:

```cmake
set_target_properties(CURL::libcurl PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
INTERFACE_LINK_LIBRARIES "lber;ldap;/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk/System/Library/Frameworks/SystemConfiguration.framework;OpenSSL::SSL;OpenSSL::Crypto;ZLIB::ZLIB"
)
```

A work-around is to link against system-level frameworks with
`-framework XYZ`. In case of `SystemConfiguration` we might be able
to omit the lookup-check because we could assume the framework is
always present.

This was previously defined by the obsolete AC_TYPE_SIGNAL macro,

So, remove it and just use void instead.

config: fix building SMB with configure using Win32 Crypto

Align conditions for NTLM features between CMake and configure
builds by differentiating between USE_NTLM and USE_CURL_NTLM_CORE,
just like curl_setup.h does internally to detect support of:

- USE_NTLM: required for NTLM crypto authentication feature
- USE_CURL_NTLM_CORE: required for SMB protocol

Implement USE_WIN32_CRYPTO detection by checking for Crypt functions
in wincrypt.h which are not available in the Windows App environment.

Link advapi32 and crypt32 for Crypto API and Schannel SSL backend.
Fix condition of Schannel SSL backend in CMake build accordingly.

cmake: correctly handle linker flags for static libs

curl CMake was setting the the EXE flags for static libraries which made
the /manifest:no flag ended up when linking the static library, which is
not a valid flag for lib.exe or llvm-lib.exe and caused llvm-lib to exit
with an error.

The better way to handle this is to make sure that we pass the correct
linker flags to CMAKE_STATIC_LINKER_FLAGS instead.
