  -----------
  [AMDGPU] Add dynamic LDS size implicit kernel argument to CO-v5 (#65273)

"hidden_dynamic_lds_size" argument will be added in the reserved section
at offset 120 of the implicit argument layout.
Add "isDynamicLDSUsed" flag to AMDGPUMachineFunction to identify if a
function uses dynamic LDS.

hidden argument will be added in below cases:

- LDS global is used in the kernel.
- Kernel calls a function which uses LDS global.
- LDS pointer is passed as argument to kernel itself.
