printf: Compile the kunit test with DISABLE_BRANCH_PROFILING DISABLE_BRANCH_PROFILING

GCC < 12.1 can miscompile printf_kunit's errptr() test when branch
profiling is enabled. BUILD_BUG_ON(IS_ERR(PTR)) is a constant false
expression, but CONFIG_TRACE_BRANCH_PROFILING and
CONFIG_PROFILE_ALL_BRANCHES make the IS_ERR() path side-effectful.
GCC's IPA splitter can then outline the cold assert arm into
errptr.part.* and leave that clone with an unconditional
__compiletime_assert_*() call, causing a false build failure.

This started showing up after test_hashed() became a macro and moved its
local buffer into errptr(), which changed GCC's inlining and splitting
decisions enough to expose the compiler bug.

Workaround the problem by disabling the branch profiling for
printf_kunit.o. It is a straightforward and acceptable solution.

The workaround can be removed once the minimum GCC includes commit
76fe49423047 ("Fix tree-optimization/101941: IPA splitting out
function with error attribute"), which first shipped in GCC 12.1.

lib/tests: add KUnit test for bitops

Add a KUnit test suite for the bitops API.

The existing 'lib/test_bitops.c' is preserved as-is because it contains
ad-hoc micro-benchmarks 'test_fns' and is intended to ensure no compiler
warnings from C=1 sparse checker or -Wextra compilations.

Introduce 'lib/tests/bitops_kunit.c' for functional regression testing. It
ports the test logic and data patterns from 'lib/test_bitops.c' to KUnit,
verifying correct behavior across various input patterns and
architecture-specific edge cases using isolated stack-allocated bitmaps.

The following test logic has been ported from test_bitops_startup() in
lib/test_bitops.c:
- set_bit() / clear_bit() / find_first_bit() validation ->
test_set_bit_clear_bit()
- get_count_order() validation -> test_get_count_order()
- get_count_order_long() validation -> test_get_count_order_long()

Also improve the find_first_bit() test to check the full bitmap length
(BITOPS_LENGTH) instead of omitting the last bit, ensuring the bitmap is
completely empty after cleanup.

Verified on x86_64, i386, and arm64 architectures.

list: add kunit test for private list primitives

Add a KUnit test suite for the new private list primitives.

The test defines a struct with a __private list_head and exercises every
macro defined in <linux/list_private.h>.

This ensures that the macros correctly handle the ACCESS_PRIVATE()
abstraction and compile without warnings when acting on private members,
verifying that qualifiers are stripped and offsets are calculated
correctly.

lib/tests: convert test_min_heap module to KUnit

Move lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it to
use KUnit.

This change switches the ad-hoc test code to standard KUnit test cases.
The test data remains the same, but the verification logic is updated to
use KUNIT_EXPECT_* macros.

Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is no
longer used. The new CONFIG_MIN_HEAP_KUNIT_TEST will be automatically
enabled by CONFIG_KUNIT_ALL_TESTS.

The reasons for converting to KUnit are:

1. Standardization:
Switching from ad-hoc printk-based reporting to the standard
KTAP format makes it easier for CI systems to parse and report test
results

2. Better Diagnostics:
Using KUNIT_EXPECT_* macros automatically provides detailed
diagnostics on failure.

3. Tooling Integration:
It allows the test to be managed and executed using standard
KUnit tools.
