fix(ivy): use globally unique names for i18n constants (#25689)

Closure compiler requires that the i18n message constants of the form

const MSG_XYZ = goog.getMessage('...');

have names that are unique across an entire compilation, even if the
variables themselves are local to a given module. This means that in
practice these names must be unique in a codebase.

The best way to guarantee this requirement is met is to encode the
relative file name of the file into which the constant is being written
into the constant name itself. This commit implements that solution.
