LOG: [TableGen] Don't use inline storage for ReferenceLocs (NFC) (#125231)

The ReferenceLocs are not enabled by default (they are used by the
tablegen lsp server), and as such always empty, but still allocate
inline storage for the SmallVector. Disabling it saves about 200MB on
RISCVGenGlobalISel.inc.

(The equivalent field in Record already disables inline storage.)

(cherry picked from commit c640f97ccf723e64ff24af225cb995c905538406)
