add generic image_builder

[nalajcie]

Description

• scripts: add image_builder
  New generic tool for generating target plo scripts and partition / disk
  images.
• scripts/g716: enhance size param parsing
• strip.py: add ELF program headers parser
• build: build host tools with ASAN disabled
  In phoenixrtos/build there is no libasan.so.8 installed by default which
  results in broken host tools.
• build.sh: set all static output dirs before sourcing target/project script
