  -----------
  [mlir][nvvm]Add support for grid_constant attribute on LLVM function arguments (#78228)

Add support for attribute nvvm.grid_constant on LLVM function arguments.
The attribute can be attached only to arguments of type llvm.ptr that
have llvm.byval attribute.
Generate LLVM metadata for functions with nvvm.grid_constant arguments.
The metadata node is a list of integers, where each integer n denotes
that the nth parameter has the
grid_constant annotation (numbering from 1). The generated metadata node
will be handled by NVVM compiler. See
https://docs.nvidia.com/cuda/nvvm-ir-spec/index.html#supported-properties
for documentation on grid_constant property.

This patch also adds convertParameterAttr to
LLVMTranslationDialectInterface for supporting the translation of
derived dialect attributes on function parameters
