Capture/Replay: Add expression trigger validation calls.

Setting the environment variable "ANGLE_CAPTURE_VALIDATION_EXPR"
will make ANGLE's capture logic evaluate this expression every
captured call to see if it should insert a validation checkpoint.

The retracing script also accepts --validation-expr as an argument.

For instance, the expression:
((frame == 2) && (call < 1189) && (call > 1100) && ((call % 5) == 0))

Will insert validation checkpoints on frame 2, between calls 1100 and
1189 and will validate every 5th call. The 'call' here is the count of
captured calls, which are mostly GL calls with a few ANGLE replay
calls in the mix.

We add a small single-header library that can evaluate arthithmetic
expressions in order to parse these expressions, as well as an option
to the retracing script.
