The test plan for TAP needs to be declared immediately after the header.
This adds the test plan API to kselftest.h and updates all callers to
declare their expected test counts.

The current mainline breakpoints test for arm64 fails to compile with
breakpoint_test_arm64.c: In function ‘set_watchpoint’:
breakpoint_test_arm64.c:97:28: error: storage size of ‘dreg_state’ isn’t known
struct user_hwdebug_state dreg_state;
Adding a direct include for asm/ptrace.h helps it to build, and passes
the test on mainline on hikey.

Convert breakpoint_test_arm64 output to TAP13 format. Use ksft_* var arg
msg api to include strerror() info. in the output. Change output from
child process to use ksft_print_msg() instead of ksft_exit_* to avoid
double counting tests and ensure parent process does the test counter
incrementing.

Make the three tests that did use the old ksft_ext_skip()
(breakpoints/breakpoint_test_arm64, breakpoints/step_after_suspend_test,
and membarrier_test) use the new one, with an output for the
reason for skipping all the tests.

ARM64 hardware expects 64bit aligned address for watchpoint invocation.
However, it provides byte selection method to select any number of
consecutive byte set within the range of 1-8.
This patch adds support to test all such byte selection option for
different memory write sizes.
Patch also adds a test for handling the case when the cpu does not
report an address which exactly matches one of the regions we have
been watching (which is a situation permitted by the spec if an
instruction accesses both watched and unwatched regions). The test
was failing on a MSM8996pro before this patch series and is
passing now.
