Add basic support to run various MIPS variants via kunit_tool using the
virtualized malta platform.
Some of the cs_dsp unittests are broken. They are being disabled by default in
the series "Fix up building KUnit tests for Cirrus Logic modules" [0].

Changes in v3:
- Also skip VDSO_RANDOMIZE_SIZE adjustment for kthreads
- Link to v2: https://lore.kernel.org/r/20250414-kunit-mips-v2-0-4cf01e1a29e6@linutronix.de
Changes in v2:
- Fix usercopy kunit test by handling ABI-less tasks in stack_top()
- Drop change to mm initialization.
The broken test is not built by default anymore.
- Link to v1: https://lore.kernel.org/r/20250212-kunit-mips-v1-0-eb49c9d76615@linutronix.de

If such a task ever ends up calling stack_top(), it will derefence the NULL ABI pointer and crash. This can for example happen when using kunit: mips_stack_top+0x28/0xc0 arch_pick_mmap_layout+0x190/0x220 kunit_vm_mmap_init+0xf8/0x138 __kunit_add_resource+0x40/0xa8 kunit_vm_mmap+0x88/0xd8 usercopy_test_init+0xb8/0x240 kunit_try_run_case+0x5c/0x1a8 kunit_generic_run_threadfn_adapter+0x28/0x50 kthread+0x118/0x240 ret_from_kernel_thread+0x14/0x1c Only dereference the ABI point if it is set. Also move the randomization adjustment into the same conditional.
