Register bp2build module types even outside generation

Without this fix, mixed builds are silently disabled, as a recent change
disabled mixed builds for all module types which are not listed in this
map. This map should be populated for both bp2build generation and for
mixed builds.

Test: lunch aosp_flame && USE_BAZEL_ANALYSIS=1 m libc
