Reduce/cordon bloat in facet, introduce bloatbench

Looks into codegen size, compile times etc. - again :) after adding a buuuunch of features.

- [x] Disable miette's default features (derive, which depends on syn) (`b.miette`)
- [x] Don't enable miette fancy by default in facet-json (`b.miette-fancy`)
- [x] Flatten closures in facet-json to avoid generic instantiations (`b.flatten-closures`)
- [x] Get rid of shape_of in Shape derive, use `#field_type` directly (`b.shape-of`)
- [x] Detect known derives in facet-macros, eschew impls! for them (`b.detect-derives`)
- [x] Gate nonzero impls, net impls (`b.gate-impls`)
- [x] Gate doc-comments, vtable-fmt, vtable-cmp, vtable-hash (`b.gate-vtable`)
- [x] Make 'auto trait detection' opt-in (`b.auto-traits-optin`)
- [x] Detect traits from `derive` and from `#[facet(default)]` (`b.derive-traits`)
- [x] Allow manual trait specification via `#[facet(traits(...))]` (`b.manual-traits`)
- [x] Go back to builders (they expand to less code) (`b.builders`)
- [x] VTable restructured with sub-vtables (`format`, `cmp`, `hash`, `markers`) (`b.vtable-substruct`)
- [x] Convert manual impls to ShapeBuilder (`scalar.rs`, `fn_ptr.rs`, `impls_num_complex.rs`) (`b.shapebuilder`)
- [x] **Confirmed**: `#![allow(uncommon_codepoints, nonstandard_style)]` in library = no warnings in consumers (`b.unicode-test`)
- [x] Add `FieldBuilder::new(name, shape_fn, offset)` builder (`b.field-builder`)
- [x] Add `StructTypeBuilder::new(kind, fields)` builder (`b.structtype-builder`)
- [x] Add `VariantBuilder::new(name, data)` builder (`b.variant-builder`)
- [x] Add `EnumTypeBuilder::new(enum_repr, variants)` builder (`b.enumtype-builder`)
- [x] Create `::facet::𝟋` module with type aliases and builder exports (`b.prelude-mod`)
- [x] Update derive macro to use builder pattern for Field, StructType, Variant, EnumType (`b.derive-builders`)

Based on analysis in `facet-bloatbench/MACRO-OPTIMIZATION-ANALYSIS.md`:

- [x] Remove `let mut vtable = const... (continued)
