  [clang][cli] NFC: Add PIE parsing for precompiled input and IR

This patch effectively reverts a small part of D83979.

When we stop parsing `LangOpts` unconditionally in `parseSimpleArgs` (above the diff) and move them back to `ParseLangArgs` (called in `else` branch) in D94682, `LangOpts.PIE` would never get parsed in this `if` branch. This patch ensures this doesn't happen.

Right now, this causes `LangOpts.PIE` to be parsed twice, but that will be immediately corrected in D94682.

  [clang][cli] NFC: Parse some LangOpts after the defaults are set

This patch ensures we only parse the necessary options before calling `setLangDefaults` (explained in D94678).

Because neither `LangOpts.CFProtectionBranch` nor `LangOpts.SYCLIsDevice` are used in `setLangDefaults`, this is a NFC.

  [clang][cli] NFC: Promote ParseLangArgs and ParseCodeGenArgs to members

This patch promotes `ParseLangArgs` and `ParseCodeGenArgs` to members of `CompilerInvocation`. That will be useful in the following patch D94682, where we need to access protected members of `LangOptions` and `CodeGenOptions`. Both of those classes already have `friend CompilerInvocation`.

This is cleaner than keeping those functions freestanding and having to specify the exact signature of both in extra `friend` declarations.
