[clang] Switch to Default PIE on FreeBSD (#206139)
We have started to compile the binary in our base as PIE by defualt. It makes sense to compile the binary to PIE by default in toolchain as Linux now. Also, extended testcases to support default PIE and no-pie parameter in freebsd.c and hip-fpie-option.hip.
