[BOLT][TEST] Import jump-table-icp.test, update link_fdata script
Summary: Import the test. The assembly input has three functions with associated fdata. The old link_fdata.sh script only replaces the symbol names with symbol values, whereas fdata format expects to have symbol offsets against the anchor symbol. Introduce the link_fdata.py script which is able to parse the input and produce either an offset or an absolute symbol value. (cherry picked from FBD32256351)
