LibJS: Add basic monomorphic caching for PutById property access
...
This patch makes it possible for JS::Object::internal_set() to populate
a CacheablePropertyMetadata, and uses this to implement a basic
monomorphic cache for the most common form of property write access.

LibJS/JIT: Resolve the PropertyLookupCache pointers at JIT time
...
We know where the lookup cache is by the time we're jitting code, so
let's put the pointer directly into the instruction stream.

when jitting the code, instead of every time GetById executes.

LibJS/JIT: Support alternative entry point blocks
...
If Interpreter::run_and_return_frame is called with a specific entry
point we now map that to a native instruction address, which the JIT
code jumps to after the function prologue.

LibJS: Lazily collect stack trace information
...
The previous implementation was calling `backtrace()` for every
function call, which is quite slow.
Instead, this implementation provides VM::stack_trace() which unwinds
the native stack, maps it through NativeExecutable::get_source_range
and combines it with source ranges from interpreted call frames.

LibJS/JIT: Provide source location information for JIT code
...
This works by walking a backtrace until the currently executing
native executable is found, and then mapping the native address
to its bytecode instruction.

LibJS: Save scheduled jumps when entering unwind contexts
...
These are then restored upon `ContinuePendingUnwind`.
This stops us from forgetting where we needed to jump when we do extra
try-catches in finally blocks.
