[llvm] [cmake] Set EXCLUDE_FROM_ALL on gtest and TestingSupport

Exclude building googletest and LLVMTestingSupport libraries from
the `all` target.  If unittests are being built, these libraries will
be built as a dependency anyway.  If they are not being built, building
them makes little sense as they are not installed or used otherwise.

This will also make standalone builds of other projects easier, as it
makes it possible to include these directories without having to cover
them with additional conditions to prevent them from being built
unconditionally.

The solution is to display presented in this patch is to display "<incomplete type>" as the summary for any incomplete types. If there is a summary string or function that is provided for a type, but the type is currently forcefully completed, the installed summary will be ignored and we will display "<incomplete type>". This patch also exposes the ability to ask a SBType if it was forcefully completed with:

  bool SBType::IsTypeForcefullyCompleted();

This will allow the user interface for a debugger to also detect this issue and possibly mark the variable display up on some way to indicate to the user the type is incomplete.

To show how this is diplayed, we can look at the existing output first for the example source file from the file: lldb/test/API/functionalities/limit-debug-info/main.cpp
