- Enable Support for L0 Function Pointers for Kernels and Exported
Functions
- Return ZE_RESULT_ERROR_INVALID_FUNCTION_NAME given no function of that
name is a kernel or exported function

- Added EnableProgramSymbolTableGeneration to enable or disable default
behavior for IGC to generate the program symbol tables for L0 modules
with exported functions.
- Default value set to true to add -library-compilation to all module
builds.

When module is created but not fully linked we don't copy ISA to GPU
however we need to store patched segments for dynamic linking

I've added debug flag FailBuildProgramWithStatefulAccess which makes
possible to fail build program/module creation
with stateful access(except builtins) on
pvc and later platforms.

- 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.

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.
