Upgrade to LLVM 17, fix linux debug build, upgrade JSC, remove some C API usages

[Jarred-Sumner]

What does this PR do?

• Upgrade from LLVM 16 -> LLVM 17
• Linux debug build works once again
• Upgrade JSC
• Replace C API usage of JSPropertyIterator with a C++ bindings one, which also avoids cloning the property names an extra time
• Adds a BunString version of JSValue.put which will be faster in most cases since it avoids atomizing the strings again
• Bunch of small changes for strings for the JSC upgrade

This won't compile until the upgraded JSC successfully compiles in CI. Tested locally.

How did you verify your code works?
