These tests aren't (directly) using Posix APIs, so they don't need to be in posix/test.zig. Put them over with the code and tests in Thread.zig. Since the spawn/join test in the posix code was redundant, just dropped that one.
Re-enable the test. Will trigger ziglang#24380 as-is, but follow-on change moes this code over to test/standalone. Make the test a bit easier to debug by stashing the "seen" signal number in the shared `seen_sig` (instead of just incrementing a counter for each hit). And only doing so if the `seen_sig` is zero.
Add build.zig, README and empty test files.

Several tests of the
std.posixAPI (including the "sigset_t bits" one) exercise global state that isn't reliably safe to use in a Zig unit test. This PR moves those cases over totest/standalone.Also, while doing this I noticed a couple std.Thread tests in with the std.posix tests, so I moved those over to be with the existing Thread tests.
Fixes #24380
