cr50: rebuild board image if essential make variables change
When building Cr50 board image, some make variables get converted into
compilation flags, which affect image composition. Changes of these
variables go unnoticed as they do not directly affect make
dependencies.
Let's define the set of essential variables in ENV_VARS, and save the
state of these variables at build time in a generated .h file,
updating it only if any of the variables' values changed since the
previous make run.
The generated .h file is included in board.h, which guarantees that
files dependent on board.h are recompiled if the generated .h file
changes.
BRANCH=cr50
BUG=none
TEST=verified that changing of CR50_DEV and/or H1_RED_BOARD or
CR50_SQA values triggers full rebuild of the Cr50 image.
Verified that 'emerge-atlas ec-utils' also succeeds.
