Handle misaligned access when aplying debug relocations in zebin.
Debug relocations entries have offsets which are not of natural
alignment, and need to be specificialy handled.

Usage of initializer list in for loop to iterate over heavy types
has bad consequences. std::initialize_list is only a view and its
data is silently created as T[N]. Therefore, if someone uses
std::vector with it, it will cause deep-copying of the elements.
This change introduces usage of pointers on std::initializer_list
to perform a shallow-copy of an addresses. Furthermore, it adds
const references in few places, where copy is not needed.

GDB requires debug zebin to be an absolute ELF. This change adds setting
symbols values to absolute addresses allowing GDB to work correctly.

debug zebin.

feat: Set text sections' addresses with valid GPU VA. Offset debug symbols
with text segment names by corresponding segment's GPU VA.

- ELF type is EXEC
- Absolute GPU addresses in program headers as load addresses
- All relocations are applied (not only for debug info as before)
- Default section alignment for debug zebin is set to 4,
this fix the problem with .notes section parsing

This commit adds debug zebin creation in OCL.
- Added returning debug zebin in build/linking paths in OCL if
corresponding device binary format was detected.
- Refactored getZebinSegments() method - added common ctor for both
L0/OCL paths
