Adds Architecture Property on defineFunction

[caioquirino]

Problem

Allows the users to choose between the available Lambda runtime architectures (x86_64 and arm64).

Issue number, if available: 1820

Changes

Corresponding docs PR, if applicable:

This is a relatively simple change, which only adds the architecture field to the defineFunction function, with x86_64 as its default value to keep backwards compatibility, and converts it to the corresponding CDK API Architecture value.

This change also introduced a new Architecture validation to guarantee that only valid values are used. Tests and documentation changes are also included.
