JS: add GHC.JS.Optimizer, remove RTS.Printer, add Linker.Opt

This MR changes some simple optimizations and is a first step in re-architecting
the JS backend pipeline to add the optimizer. In particular it:

- removes simple peep hole optimizations from `GHC.StgToJS.Printer` and removes that module
- adds module `GHC.JS.Optimizer`
- defines the same peep hole opts that were removed only now they are `Syntax -> Syntax` transformations rather than `Syntax -> JS code` optimizations
- hooks the optimizer into code gen
- adds FuncStat and ForStat constructors to the backend.

Working Ticket:
- #22736

nonmoving: Account for mutator allocations in bytes_allocated

Previously we failed to account direct mutator allocations into the
nonmoving heap against the mutator's allocation limit and
`cap->total_allocated`. This only manifests during CAF evaluation (since
we allocate the CAF's blackhole directly into the nonmoving heap).

Fixes #23312.

compiler: Fingerprint more code generation flags

Previously our recompilation check was quite inconsistent in its
coverage of non-optimisation code generation flags. Specifically, we
failed to account for most flags that would affect the behavior of
generated code in ways that might affect the result of a program's
execution (e.g. `-feager-blackholing`, `-fstrict-dicts`)

Closes #23369.
