Separate hidden API flag info for sdk from platform_bootclasspath

Previously, the sdk snapshot and platform_bootclasspath both used the
HiddenAPIInfo/Provider to retrieve the hidden API related information
they needed. This change separates them by adding a new
HiddenAPIInfoForSdk/Provider that is used to provide the information
needed by the sdk snapshot. This allows a follow up change to generate
different information for the sdk and for the platform depending on the
target build release of the sdk snapshot.

Bug: 240406019
Test: packages/modules/common/build/mainline_modules_sdks.sh
      # Ran the previous command with and without this change to make
      # sure that this change does not change the sdk snapshot
      # contents.
