Remove 'const' prefix from functions that return BorderValue by value.

Remove 'const' prefix from functions that return BorderValue by value.

There are several functions that create a BorderValue and return it by
value. However, the return type is 'const BorderValue' not 'BorderValue'
which makes it confusing because the 'const' is extraneous. This patch
removes the 'const' prefix.
