Andreas Kling 5e481950f8 LibJS: Make GetById and GetByValue avoid get_identifier() in common case ...

cases like when a property access is cached.

(cherry picked from commit 509c10d14db0f2e2ce2b89f307d9dd360b855eb5,
amended to mark the two `throw_null_or_undefined_property_get` functions
static, as -Wmissing-declarations pointed out on CI)
