  [Clang][Interpreter] Respect default setting on Windows

MSCV does not support the -fPIC option. When it is passed, Clang falls
back to PIC level 2 on x86_64 and to a static binary on AArch64. Without
-fPIC, however, PIC is already enabled by default on both targets.

As a result, the PCH (built with the default PIC level by toolchain
hint) and the clang-repl instance (using the fallback PIC level) end up
with different PIC settings, consuming a mismatch.

Avoid passing -fPIC when targeting MSVC on Windows. This preserve the
existing semantics, since PIC is already enabled by default, while
ensuring that both the PCH and clang-repl use the same PIC level.
