Replace PlatformKind with PlatformType.

The PlatformKind/PlatformType enums contain the same information, which requires
them to be kept in-sync. This commit changes over to PlatformType as the sole
source of truth, which allows the removal of the redundant PlatformKind.

The majority of the changes were in LLD and TextAPI.
