  [orc-rt] Add gmock matchers for Error and Expected<T> (#225596)

Ports llvm/Testing/Support/Error.h to orc_rt: EXPECT_THAT_ERROR and
ASSERT_THAT_ERROR, EXPECT_THAT_EXPECTED and ASSERT_THAT_EXPECTED, and
the Succeeded, Failed, Failed<InfoT>, FailedWithMessage and HasValue
matchers.

Two departures from the original. An orc_rt Error carries at most one
ErrorInfoBase -- there is no joinErrors -- so the holder keeps a single
error, FailedWithMessage takes one matcher rather than a variadic pack,
and FailedWithMessageArray is dropped. ErrorInfoBase has
dynamicRTTIName, so a type mismatch names the type that did turn up
rather than reporting only that the expected one was absent.

Header-only, under test/unit with the other test helpers rather than in
a shipped testing library. ErrorMatchersTest exercises each matcher
against a matching and a non-matching value, the latter through gtest's
failure interception.
