Andreas Kling cd2576c031 LibJS: Mark block-scoped function declaration locals as initialized ...

When emitting block declaration instantiation, we were not calling
set_local_initialized() after writing block-scoped function
declarations to local variables via Mov. This caused unnecessary
ThrowIfTDZ checks to be emitted when those locals were later read.

Block-scoped function declarations are always initialized at block
entry (via NewFunction + Mov), so TDZ checks for them are redundant.
