This change replaces mechanism of patching global constants and
variables in kernel per relocation to patching them only once. This
would improve linking time performance for kernels with multiple global
symbols.

Automatically add "-s" (source path) option if -g flag is present.
This applies only to non-spirv input.
- Due to conflict, do not automatically append source path when
CMC compiler is used.
- Minor code refactor: use defined compiler options instead of local
strings; wrap filename in quotes (in case of space-separated filename
string).

Discarding RAII lock returned from function almost always
is a bug. This change introduces usage of [[no_discard]]
attribute from C++17 to prevent such misues.

This change:
- removes redundant copying of std::vector
- removes unneeded includes from the header file
and introduces usage of forward declaration

When header is included for the first time in translation unit,
then preprocessor simply copy-pastes its content. If we define a
constant in a header file and this constant has internal linkage
then each and every translation unit, which includes this header
will have its own copy of this constant.
C++17 introduces inline variables, which are meant to allow creation
of variables in header files, which do not cause multiple instances.
The inline variable has a single instance when:
- constexpr is used without static (constexpr implicitly implies inline)
- inline is used without static
- inline const is used without static (const does not imply internal linkage
when used with inline)

This commit removes early fail in linking with zebin and external
functions which happens when, there's a relocation to external functions
section, but it's not modifying any external function. And only treats
GLOBAL FUNC symbols pointing to external functions section as external
function symbols.

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.
