Add pod specs for AmazonChimeSDKMachineLearning (aws#467)

Summary:
Add `AmazonChimeSDKMachineLearning*.podspec` files for bitcode and
non-bitcode versions. Dependencies are subsequently added to
`AmazonChimeSDK`. Although developers don't necessarily need the
library, this makes sure that if they want to use the features, the
transitive dependency is also imported.

Test Plan:
Verify that `AmazonChimeSDKDemoPods` works through localhost and a
private podspec repository.
