feat(mem-analysis): Adding Dockerfile_with_heaptrack (#1681)

* Adding Dockerfile_with_heaptrack

* build: merge heaptrack dockerfile with production dockerfile (#1682)

* Avoid blindly copy /usr/lib/ and install only the needed libraries

* Adding heaptracker options in the Makefile

* Dockerfile simplification. (apk add libunwind)

* Dockerfile, Makefile: ++heaptrack params to nim build & 'heaptrack_support' in Nim compiler

* Dockerfile, Makefile: more convenient name for 'NIM_COMMIT' Docker arg

* Making 'NIM_COMMIT' more explicit
