Support dynamic parameters

[AutonomicPerfectionist]

Description Adds support to CMinx to document dynamically generated function and macro parameter names. For example:

set(MyFunctionParamName "Name_Of_A_Param")

#[[[
# This is a documented function, but the first parameter name
# is dynamically assigned.
#]]
function("function_with_var_param_name" "${MyFunctionParamName}")
endfunction()

The above will now be documented as the following RST:

.. function:: "function_with_var_param_name"("${MyFunctionParamName}")

   This is a documented function, but the first parameter name
   is dynamically assigned.

This has been verified to work with Sphinx version 4.5.0 with the default theme
