Prepare cache setup and reservation logic to be extended w.r.t other
cache-levels.
Conceptually this change is like adding a switch-statement, in several
places, in which existing code makes a single (and only) case. This is
caused by splitting larger development to ease the review. Further cases
will be added in following steps. Such approach sometimes creates code
which may seem redundant but it is meant to simplify plugging following
extensions in an easy way.

Fix the PAT-index reporting in logger as currently on Windows reported
values are simply wrong.
The changed logic dependends on `RootDeviceEnvironment` and in order to
avoid introducing such dependencies into logger.[ch] the
`logAllocation()` is no longer a member of `FileLogger` but
a free-function instead (and a separate .cpp file). This is important
because the source files `logger.[ch]` are also used by ocloc library
and there is no point to contaminate ocloc code structure with
unnecessary dependencies.
