This change prevents embedding identical SPIR-V section for each
target requested in fatbinary build. Instead of duplicating SPIR-V,
a new file called 'generic_ir' is added to AR archive. It contains
SPIR-V, which was used to build fatbinary. Build fallback in runtime
has been also adjusted - if 'generic_ir' file is defined in fatbinary
and there is no matching binary, then this generic SPIR-V is used to
rebuild for the requested target.
Additionally, MockOclocArgumentHelper::loadDataFromFile() was adjusted
to ensure null-termination of returned strings.
This change also removes possible undefined behavior, which was
related to reading names of files from AR archive. Previously,
if filename was shorter than requested target name, we tried to
read more memory than allowed.

- 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

If a kernel has ray tracing calls, we allocate and initialize
per-device RTDispatchGlobals if needed, and hand off pointer to
the same into a running kernel via an implicit parameter.
