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.

getLoadedLibVersion is intended for reading version of a library that was
already loaded into the process prior to this call (i.e. new instance of
the library willnot be loaded).
Note: Currently, only windows version of this functionality is implemented.

eudebug interface is now hidden under EuDebugInterface class
shared code uses generic object and param values
layout of structs is guarded by static asserts
eudebug support is guarded by cmake flags:
- NEO_ENABLE_XE_EU_DEBUG_SUPPORT - enables eudebug in general
- NEO_USE_XE_EU_DEBUG_EXP_UPSTREAM - registers exp upstream uAPI support
- NEO_ENABLE_XE_PRELIM_DETECTION - registers prelim uAPI support
This way we can support two different xe-eudebug interfaces within
single binary.
In unit tests there is mock eudebug interface enabled (even if no
eudebug support is enabled by cmake flag).

Leverage features of the mechanism to simplify implementation:
- The maximum number of possible cache-region reservations is a small
value known at compile-time
- Each reservation is unique (described by `CacheRegion`) so can have
a dedicated entry with either zero (free) or non-zero (reserved) value
So, there is no need for a dynamic collection (unordered_map here) to
keep track of reservations. A simple array is enough for that purpose.
Also, add some helper-code to enable array-indexing with the values of
`CacheRegion` enum.
