Enforce apex.min_sdk_version for bundled builds
Previously, when Q-targeting apexes are bundled-built, they are built
against the latest stubs.
It was because unwinder is linked dynamically in R and APIs are provided
by libc while Q apexes should run on Q where libc doesn't provide those
APIs. To make Q apexes run on Q device, libc++ should be linked with
static unwinder. But, because libc++ with static unwinder may cause problem
on HWASAN build, Q apexes were built against the latest stubs for bundled
build.
However, Q apexes should be built against Q stubs.
Now, only for HWASAN builds, Q apexes are built against the latest stubs
(and native modules are not linked with static unwinder).
Bug: 151912436
Test: TARGET_SANITIZE=hwaddress m
=> Q apexes(media, resolv, ..) are linked with the latest stubs
m
=> Q apexes are linked with Q stubs,
and Q apexes' libc++ is linked with static unwinder
