[Pytorch][Vulkan] shader codegen use ordered dictionary (#89951)
When not using ordered dictionary, it can result in parameter values have
different order for each specialization. This can result shader names which are
not consistent in their naming and meaning of the template parameter values
that appear in the meaning of their names.
For example if you have:
conv2d_pw:
default_values:
- X: 1
- Y: 2
parameter_values:
- Y: 3
Default parameter value can generate shader with 'my_shader_1x2' where 1x2 is
for X, Y parameters respectively. Then,
for non default values, of which there is only 1, we have Y=3 and with existing
implementation you can end up genreating shader with 'my_shader_3x1'. Here 3 is
for Y and 1 is for X. This leads to confusing shader names.
THis diff fixes this by
1. using ordered dict.
2. non default values are updated by first copying default values and then
updating them.
