Fix Python HAL device creation params only last one used (#24812)

While using the Python bindings for the IREE runtime, I noticed that
only the last key-value pair in the dictionary passed as the `params`
argument to HalDriver's `create_device` method is actually consumed.

In the code below, pointers created using `c_str()` from the elements of
`param_strings` are stored in `passed_params`, but the issue is that if
`param_strings` is reallocated, those pointers become invalid.


https://github.com/iree-org/iree/blob/3c2a79f36e8b3333ffebb55c4afef1798581ccb5/runtime/bindings/python/hal.cc#L1133-L1145

In this PR, prevent reallocation by reserving the necessary space for
`param_strings` in advance.
