To repro, on an XFA-enabled build:

1. Open the attached imm5257e_filled_dummy.pdf.
2. Press the Validate button.
Expected: No JS error messages.
Actual: In debug, a message saying "JS Error: TypeError: console.show is not a function" appears.

"console" is defined by V8. It can be overridden with an instance that contains "show". Not sure if this is actually necessary to make this form's validation work, since it's in the catch block.

I don't think anymore this should block XFA, though it would avoid breaking scripts that have console.show() calls left from debugging.

Make built-in JS console compatible with Adobe's console.

console.show() and console.println() are calls commonly found in XFA
scripts. This CL adds methods to the built-in V8 console so these calls
do not stop the rest of script from running.
