vkd3d-shader/hlsl: Split declare_vars().

Basically, declare_vars() is separated in three functions:

1. check_invalid_in_out_modifiers(), which is to be called once per
   declaration and emits an error when in or out modifiers are used for
   these non-parameter variables.

2. declare_var(), which now handles one variable at the time and doesn't
   free any memory.

3. initialize_vars(), which takes care of preparing the initialization
   instructions of several variables and frees their struct
   parse_variable_def, using exclusively free_parse_variable_def().

This allows to declare variables individually before the initializer of
the next variable in the same declaration is parsed, which is used in
the following patches.

Also, simplifies memory management.
