iOS: Migrate to build with SPM + Bazel

[hborawski]

Migrate away from CocoaPods as a package manager, and build through SPM

We will still publish to CocoaPods but we do not need to build and resolve our dependencies through it, as it complicates usage of Bazel

wip on https://github.com/player-ui/player/tree/spm-bazel-6

on https://github.com/player-ui/player/tree/bazel-6

bazel build //:PlayerUI_Pod

will build a SPM compatible zip

zip contents still needs to be published to a separate repo so the JS files will be present in the git location

any update for swift support?

@fangmobile No update since the last comment

SPM support is 99% complete, just need to publish it, but we need to get android migrated to bazel-6 to get us to the publishing stage, and that work is in progress currently
