the androidboot.microdroid.mount_vendor=1 is provided in the kernel
cmdline.

The existing approach in first_stage_init/first_stage_mount makes it
harder to add conditional logic that should only be applied for
Microdroid. Additionally, it forces the FirstStageMount object to be
created twice.
This change refactors the control flow to make first_stage_init take the
ownership of the FirstStageMount object. It will help with the follow up
change (which will add logic to conditionally mount /vendor partition
while booting Microdroid). As a nice side effect, this refactoring also
fixes the problem of the FirstStageMount being created twice.
This change also merges the FirstStageMount and FirstStageMountVBootV2
in a single class, since nobody actually uses FirstStageMount.

The variant excludes the code that is not for /proc/mounts, and
therefore saves code size when being called.
Also, after this change, the call to `SkipMountingPartitions` is skipped
for /proc/mounts because it is not needed.

We are now conditionally compiling init binaries & libinit for
Microdroid (adding -DMICRODROID=1 cflag), so instead of checking for the
presence of the /system/etc/selinux/microdroid_precompiled_sepolicy we
can check if the code is compiled for Microdroid.
In a follow-up changes we can split the sepolicy loading logic into 2
separate headers (one for Android and one for Microdroid) and include
the necessary one depending on the target we compile for.
