- Allow for all exported symbols between L0 Dynamically linked Modules
to be accessible by adding the exported function allocations to all
linked modules unconditionally.
- This enables for L0 Function Pointers to be used to call functions
between the modules without unresolved symbols, which were a condition
to allow for exported allocations to be accessed between modules.

This change:
* Adds support for build options section in zebinary - using
build options in binary when rebuilding.
* Appends "-cl-intel-allow-zebin" flag to build options when zebin is
used.

- Added support for Dynamic Module link to allow usage of
symbols that exist thru a circular dependency from the export->import
module & chained dependencies with importModule -> ExportModule ->
ExportModule2.
- Adds a dependency walker which collects all dependent modules whose
export surface state must be made resident for a given kernel
execution to successfully access each function resolved on different
modules.
- Expanded the Dynamic Link Black Box test to allow for testing either
simple linking and circular + chained linkage.

After this change driver will fail clBuildProgram/zeModuleCreate api calls
whenever stateful access is discovered on PVC.
This is required since in this case allocation greater than 4GB
will not work.
If user still wants to use stateful addressing mode,
-cl-opt-smaller-than-4GB-buffers-only / -ze-opt-smaller-than-4GB-buffers-only
build option should be passed as build option, but then user can not use
bufers greater than 4GB.

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.

Introduced a new warning, which is printed to build log, when the
binary needs to be recompiled. Added a new flag -Wno-recompiled-from-ir
to allow suppression of that message. Removed a bug related to memcpy_s
from ModuleBuildLogImp::getString() and aligned it with specification.

- Support for L0 apps to handle undefined symbols reported by IGC
- Removed duplication of symbol in exported symbol list and relocation
for properly resolving the symbol during dynamic link
- Add export module's exported function surface state to the import
module's residency container during dynamic linkage to allow import
kernels to execute exported functions.
