[ios] Update TOS promo string

Previously, the string with IDS_IOS_REVIEW_UPDATED_CHROME_TOS
was made to differentiate between Chrome and Chromium.
This string should never refer to Chromium. It is only valid
with regards to Chrome. Therefore, the string should be defined
in the file ios_strings.grd.

This change was requested by Legal to ensure that no user is ever
told that Chromium TOS has changed.

This CL defines IDS_IOS_REVIEW_UPDATED_CHROME_TOS in ios_strings.grd,
and removes this ID from ios_chromium_strings.grd and
ios_google_chrome_strings.grd.
