Move apex module installation into Soong 

Move apex module installation rules into Soong by overriding
InstallBypassMake.

Soong installs don't support post install commands, so move the
symlinks into separate rules and add dependencies on them.

This relands If65d283abc86f18ad266da0bf16fe95971a0bf9c with fixes
to install files into $OUT/apex.

Bug: 204136549
Test: m checkbuild
