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: Store the bytecode accumulator in a dedicated physical register
...
We now use a dedicated physical register to store the bytecode
accumulator, instead of loading and storing it to the memory everytime.

LibJS: Avoid crash on empty stack trace
...
We were trying to stringify the stack trace without the last element,
leading to a loop bound of (size_t)(0 - 1) and accessing m_traceback[0]
out-of-bounds.
Instead, just return an empty string in that case.
Fixes #21747

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+Embedders: Unify stack trace format for uncaught errors
...
Previously these handlers duplicated code and used formats that
were different from the one Error.prototype.stack uses.
Now they use the same Error::stack_string function, which accepts
a new parameter for compacting stack traces with repeating frames.

These are then restored upon `ContinuePendingUnwind`.
This stops us from forgetting where we needed to jump when we do extra
