Addresses regressions from the reverted merge
of the tbx fault manager for host memory.
This fixes attempts by the tbx fault manager
to protect/unprotect host buffer memory, even
if the host ptr was not driver-allocated.
In the case of the smoke test that triggered
the critical regression, clCreateBuffer was
called with the CL_MEM_USE_HOST_PTR flag.
The subsequent `mprotect` calls on the
provided host ptr then failed.

Track amount of created buffer pools per device. Do not allocate extra
pools if limit is reached. New contexts will have pooling disabled if
limit is reached on device.

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).

In TBX mode, the host could not write to host buffers after access from device
code due to the lack of a migration mechanism post-initial TBX upload.
Migration is unnecessary with real hardware, but required for TBX.
This patch introduces a new page fault manager type that extends the original
CPU fault manager, enabling automatic migration of host buffers in TBX mode.
Refactoring was necessary to avoid diamond inheritance, achieved by using a
template parameter as the base class for OS-specific fault managers.

When debug flag ForceZeroCopyForUseHostPtr is set, add
CL_MEM_FORCE_HOST_MEMORY_INTEL flag to buffers created with
CL_MEM_USE_HOST_PTR.
This makes the buffers use zero copy.
