[SPIR-V] Change a way SPIR-V Backend API works with user facing options (#124745)

This PR fixes https://github.com/llvm/llvm-project/issues/124703:
* added a new API call `SPIRVTranslate` that is to replace entirely old
`SPIRVTranslateModule` after existing clients switch into the new
function;
* the new `SPIRVTranslate` doesn't require option parsing, replacing the
`Opts` argument with explicit `CodeGenOptLevel` and `Triple` arguments;
* the old `SPIRVTranslateModule` call is a wrapper for `SPIRVTranslate`,
it doesn't require option parsing either and doesn't hold any logic
inside except for converting string options into `CodeGenOptLevel` and
`Triple` arguments;
* usage of the extensions list is reworked to avoid writes to the global
cl::opt variable `lib/Target/SPIRV/SPIRVSubtarget.cpp::Extensions` --
instead a new class member in SPIRVSubtarget.cpp is implemented that
allows to replace supported extensions after SPIRVSubtarget.cpp is
created;
* both API calls don't require option parsing and don't write to global
cl::opt variables.

Other related/required changes:
* SPIRV::Capability::Shader is marked as an capability of lesser
priority for OpenCL environment (to remediate absence of the
"avoid-spirv-capabilities" command line option in API calls);
* unit tests are updated and extended to cover testing of a newer API
call;
* old API call is marked with TODO to remove it after existing clients
switch into the new function.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
