This patch add new environment variables to control compiler cache.
Works as follow: If persistent cache is set driver check if NEO_CACHE_DIR
is set. If not then driver checks XDG_CACHE_HOME - If exists
then driver create neo_compiler_cache folder, if
not then driver checks HOME directory. If each NEO_CACHE_DIR,
XDG_CACHE_HOME and HOME are not set then compiler cache is disabled.
Current support is for Linux only.

- set by default flag ZebinIgnoreIcbeVersion to true
- for zebin icbe version check is only inside flag
- only when use patchtoken then check icbe version is mandatory

Current flow will be to have one synchronization point
config.file. Read remains unblocking, only write(caching)
operation will be blocking (lock on config.file)

In rare case of multiple threads trying to set fclBaseTranslationCtx,
there was a potential for use after free (double delete) on
std::unique_ptr::reset.

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.

Define single .clang-tidy configuration with all used checks and use
NOLINT to selectively silence tool. That way cleanup should be easier.
third_part/ has its own configuration that disables clang-tidy for this

feat(zebin): Use addend from RELA sections when performing relocations.

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.
