Generating boot image requires a .prof file provided by the ART apex.
When building with prebuilts, this comes via the
prebuilt_bootclasspath_fragment module, which acts as a shim for
prebuilt_apex/apex_set. If we have multiple prebuilt apexes in the tree,
this shim becomes 1:many. This CL prepares dex_bootjars to select the
right .prof file when multiple prebuilts exist.
Implementation details
- Update deps mutator of dex_bootjars to create a dep on
all_apex_contributions. The latter contains information about which
apex is selected in a specific release configuration. dex_bootjars
will create a dependency on the selected apex in a postdeps phase
mutator.
- All apex module types (apex, prebuilt_apex and apex_set) will set a
provider that contains info about the location of the .prof file on
host
- dex_bootjars will access the provider of the selected apex to get the
location of the .prof file
This CL does not drop the old mechanism to get the .prof file (i.e. by
creating a dep on {prebuilt_}bootclasspath_fragment). Once all mainline
modules have been flagged using apex_contributions, the old mechanism
will be dropped

Convert all of the callers of SetProvider to use the type-safe
android.SetProvider API.

Convert all of the callers to NewProvider and NewMutatorProvider
to use a generic type parameter instead of an example object.

This will be a container for the the apex_contributions
selected using build flags. This module will be used to query the state of
selected apex contributions instead of a global that can be mutated by
anyone.
It will set a provider containing metadata for source vs prebuilts
selection. To reduce the overhead of a new mutator, this will be done in
the existing `prebuilt_select` mutator.
It will validate that there are no dups (`foo` and `prebuilt_foo` cannot
be both selected)

This module type does not any build actions, but provides metadata about
the contributions of the mainline module to other mainline modules/
platform. One immediate use case for this metadata is source vs
prebuilts selection
Each mainline module can have more than 1 metadata modules. Static build
flags will be used to select the right one in trunk.bzl, next.bzl, ...
