Migrate all Kokoro build scripts over to use the docker VM image (#4114)

* Work around GCC-9 warning treated as error ``` ../source/opt/instruction.h:101:23: error: '*((void*)& operand +32)' may be used uninitialized in this function [-Werror=maybe-uninitialized] 101 | uint64_t result = uint64_t(words[0]); ``` * Migrate all Kokoro build scripts over to use the docker VM image Required updating the NDK SDK and build scripts, as well as the check_copyright for handling 2021.
