chromecast: Restore CastContentClient::GetDataResourceBytes

Since 7c48a70 ("Compression of IDR_SECURITY_INTERSTITIAL_HTML and
modified compression function.") cast devices fail to boot in a crash
loop since CastContentClient::GetDataResourceBytes was removed
incorrectly. Add it back.

Bug: b/139161866
Test: boot
