rust: Oe-selftest fixes for rust v1.76

Add the failing tests in rust v1.76 to the exclude list
and add "ignore" tags to ignore failing unit test cases.

+Backport the patch for "ensure std for cross-targets".
+
+Previously, doing `x test compiler/*` would fail the build due to missing std.
+This change ensures that it is prepared.
+
+Also, add "[ignore]" tags to the failing unit tests to
+ignore them during rust oe-selftest.
