Improve robustness of test_all_stats_usage test. Test was relying on a
fact that system did not go to idle before this test is run. It means
that it was assuming that it will be the first test which might not be
true. Additionally, on some targets there might be some idle waits
during system boot. Test is adjusted to validate gathered statistics
with an assumption that there might have been idle period prior to the
test.

Mostly a revert of commit b1def7145f ("arch: deprecate `_current`").
This commit was part of PR #80716 whose initial purpose was about providing
an architecture specific optimization for _current. The actual deprecation
was sneaked in later on without proper discussion.
The Zephyr core always used _current before and that was fine. It is quite
prevalent as well and the alternative is proving rather verbose.
Furthermore, as a concept, the "current thread" is not something that is
necessarily architecture specific. Therefore the primary abstraction
should not carry the arch_ prefix.
Hence this revert.

`_current` is now functionally equals to `arch_curr_thread()`, remove
its usage in-tree and deprecate it instead of removing it outright,
as it has been with us since forever.

This commit relaxes the idle event statistics test precision requirement
for emulated QEMU targets because the cycle counts may be inaccurate when
the host CPU is overloaded (e.g. when running tests with twister) and a
high failure rate is observed for this test in the CI.

Test was previously relaxed for RISCV machine timer. I have a
platform where it fails on RISCV requiring further relaxation.
Relaxing precision for RISCV architecture.

Add a bunch of missing "zephyr/" prefixes to #include statements in
various test and test framework files.

This commit relaxes the precision requirements for idle event statistic
test when RISC-V machine timer driver is used. This is needed for some
platforms (e.g. hifive1), for which the cycle count is too low to pass
the checks where a percent deviation of peak cycles count is allowed.

As the type of A(n) is integer, and A3 and A5 are close to
each other. Sometimes A3 is equal to A5. So change the ">" to
