symbols/us(dvorak-intl): add placeholder characters to levels 3 and up, define `<LSGT>` for complete parity with us-intl
This change duplicates keysyms from levels 1 and 2 onto levels 3 and 4 for those with no other definitions, and also explicitly defines <LSGT> to backslash, bar, backslash, bar to complete the parity with the QWERTY version of us-intl, making it a true 1:1 permutation of the original.
