  [LoongArch] Fix GOT usage for `non-dso_local` function calls in large code model

This commit fixes an issue in the large code model where non-dso_local
function calls did not use the GOT as expected in PIC mode. Instead,
direct PC-relative access was incorrectly applied, leading to linker
errors when building shared libraries.

For `ExternalSymbol`, it is not possible to determine whether it is
dso_local during pseudo-instruction expansion. We use target flags to
differentiate whether GOT should be used.
