target/espressif: add algorithm support to execute code on target

Browse Source 
This functionality can be useful for;
1-ESP flashing code to load flasher stub on target and
write/read/erase flash.
2-ESP GCOV command uses some of these functions to run
onboard routines to dump coverage info.

This is high level api for the Espressif xtensa and riscv targets
