Enforces the time unit being returned and also allows using the standard
time utilities to manipulate it.

Gets rid of the need to hardcode the type in multiple places. This will
now be deduced automatically, based off the elements in the container
being provided to the algorithm.

Avoids propagating logging macros and facilities to files that may not need them.
This also allows hiding an internal constant.

* Fixes some cast warnings, partially fixes citra #3064

* Converted casts to uint32_t to u32

* Ran clang-format

* CoreTiming: New CoreTiming; Add Test for CoreTiming

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

These are only used in this translation unit.

Implemented the required calls to make it work.

CoreTiming: Added a new logging class Core_Timing.
