feat: use classes for structs in Python (#3232)

Update jsii to 0.14.0 to achieve the following:

- Structs are now modeled as regular classes instead of
  TypedDicts, making their use more straightforward and
  snake_casing the attribute names.
- Fix an issue where passing a variadic function taking
  structs would ignore its variadicness.
- Generate ReST-style docstrings instead of Google-style
  docstrings for maximum IDE compatibility
- Rectify the casing of the "MiB" suffix at the end
  of ECS constructs (used to be converted to `_mi_b`, now
  converted to `_mib`).

camelCased dicts can still be passed, but instantiating
classes with snake_cased constructor arguments is preferred.

BREAKING CHANGES:

* **Python**: `memory_limit_mi_b` and others are now named
  `memory_limit_mib`.
