sched: Reverse runqueue order when CLZ is available
...
This commit reverses the runqueue_cache bit order when the architecture
has a CLZ (count leading zeros) instruction. When the architecture
supports CLZ, it is faster to determine the most significant set bit of
a word than to determine the least significant bit set. Unfortunately
when the instruction is not available, it is more efficient to determine
the least significant bit set.
Reversing the bit order shaves off another 4 cycles on the same54-xpro.
From 147 to 143 ticks when testing with tests/bench_sched_nop.
Architectures where no CLZ instruction is available are not affected.

It can be desirable to not have the boot message printed each time
(e.g. logs are transferred over a wireless link on battery) while
still retaining the ability to receive INFO level logs.
This adds the option to disable the boot-up message (and also to customize
it if that is desireable).

An interrupt serviced during the idle sleep can re-request a context

core/include: Don't use 64 bit for MHZ & MiB macros
...
Those macros are all about convenience. However, always using 64 bit makes casts
nececcary that goes against the idea of having a convenience macro.
E.g. when printing a frequency in KHZ one might want to do
printf("freq: %lu kHz\n", freq / KHZ(1));
leads to an error
> error: format '%lu' expects argument of type 'long unsigned int', but argument 2 has type 'long long unsigned int'
Now we would have to cast - `%llu` is not available with newlib-nano and wholly
uneccecary.
Only use 64 bit artithmetic where necessary (GHZ, GiB), not for smaller units.

core/schedstatistics: refactor
...
- add init_schedstatistics function to be called after
auto_init, that way xtimer_is init is called before
the first call to xtimer_now
- register schedstatics code as a callback to be executed
on each sched_run()

core: Fix undefined behaviour in C11 atomics
...
Casting pointers to volatile memory to pointers to regular memory is permitted,
but using those pointers to access the memory results in undefined behavior.
This commit changes the casts to no longer drop the volatile qualifier.

core/atomic_c11: fix declarations
...
gcc 9 started complaining about type mismatches:
1. all int sized return types are expected to be
"unsigned int" instead of e.g., "uint32_t"
2. all arguments are expected to be passed as (volatile)
void * pointers
This commit fixes 1. by doing ifdef'ed typedefs for I2 and I4, an fixes
2. by using void pointers, then casting within the template bodies.

core: Made thread state an enum
...
- Introduced enum type `thread_state_t` to replace preprocessor macros
- Moved thread states to `sched.h` for two reasons:
a) Because of the interdependencies of `sched.h` and `thread.h` keeping it in
`thread.h` would result in ugly code.
b) Theses thread states are defined from the schedulers point of view, so it
actually makes senses to have it defined there

error.
