This commit adds support for handling local symbols.
* Added 2 fields to SymbolInfo - binding, and associated
instructions segment id.
* Simplified code for decoding elf symbols and relocations.
* Simplified code for patching instruction segments.
* Changed logic of decodeElfSymbolTableAndRelocations:
* Add every global symbol to symbol map.
* Add any local symbol used by relocation to symbol map.
* Changed logic of link:
* After performing relocations remove local symbols from map.
* Replaced UNRECOVERABLE_IF with returning error.
* Removed LocalSymbolInfo structure used before for local kernel jumps.
* Removed old tests.

This commit adds support for parsing SHT_NOBITS zebin's ELF sections
(containing global/constant zero-initialized data).
- Correction: in CTNI path, do not add related symbol if surface has not
been allocated.

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)
