Support generating module_info.json in Soong

Generate module_info.json for some Soong modules in Soong in order to
pass fewer properties to Kati, which can prevent Kati reanalysis when
some Android.bp changes are made.

Soong modules can export a ModuleInfoJSONProvider containing the
data that should be included in module-info.json.  During the androidmk
singleton the providers are collected and written to a single JSON
file.  Make then merges the Soong modules into its own modules.

For now, to keep the result as similar as possible to the
module-info.json currently being generated by Make, only modules that
are exported to Make are written to the Soong module-info.json.

Bug: 309006256
Test: Compare module-info.json
