1dfb0cd703 [libc] Fix wrappergen_test.cpp on runtimes build 
The `tools` directory depends on `llvm_gtest` which is not immediately
availible with a runtimes build. This patch builds the `llvm_gtest`
target if it isn't present. Additionally, we use the CMake binary
directory to find the tool binary, which is different when using a
runtimes build. Using the LLVM binary directory should match both build
conditions.

5d6ed9ff0c [libc][Obvious] Fix the build after e748db0f7f0971dc258c6631ae1fb0a38cfdf9dd. 
That changed some parts of the Support API to use std::optional instead
of llvm::Optional. This patch updates the libc uses to the new API.

1df0dbfcb5 [libc][NFC] add "LlvmLibc" as a prefix to all test names 
Summary:
Having a consistent prefix makes selecting all of the llvm libc tests
easier on any platform that is also using the gtest framework.
This also modifies the TEST and TEST_F macros to enforce this change
moving forward.

9ab6c1a99f [libc] Let wrappergen pick LLVM libc mangled name from aliasee file. 
Along the way, made a change to run tool unittests when the target
"check-libc" is run by introducing a libc testsuite for tool unittests.
