  Log Message:
  -----------
  [mlir][llvm][x86vector] One-to-one intrinsic op interface (#140055)

Adds an LLVMIR op interface that can used by external operations to
model LLVM intrinsics. Related 'op to llvm.call_intrinsic' rewriter
helper is moved into common LLVM conversion patterns. The x86vector
dialect is refactored to use the new common abstraction.

The one-to-one intrinsic op is tied to LLVM intrinsic call semantics.
Thus, the op interface, previously defined as a part of x86vector
dialect, is moved into the LLVMIR interfaces to allow other low-level
dialects to define operations abstracting specific intrinsic semantics
while minimizing infrastructure duplication.
