  [SPIR-V] Expose an API call to initialize SPIRV target and translate input LLVM IR module to SPIR-V (#107216)

The goal of this PR is to facilitate integration of SPIRV Backend into
misc 3rd party tools and libraries by means of exposing an API call that
translate LLVM module to SPIR-V and write results into a string as
binary SPIR-V output, providing diagnostics on fail and means of
configuring translation in a style of command line options.

An example of a use case may be Khronos Translator that provides
bidirectional translation LLVM IR <=> SPIR-V, where LLVM IR => SPIR-V
step may be substituted by the call to SPIR-V Backend API, implemented
by this PR.
