  Log Message:
  -----------
  [MLGO] Gate model tests on optimization-specific lit features (#217906)

### Context

`have_mlir_lowering` only indicates that `LLVM_MLGO_MODELS` is
non-empty. It does not identify which model type was compiled.

### Motivation

An inliner-only configuration incorrectly enabled regalloc-specific test
commands, and vice versa.

### Changes

Add `have_mlir_lowering_inliner` and `have_mlir_lowering_regalloc` lit
features derived from the corresponding model-generation targets. Update
MLGO tests to use the appropriate model-specific feature, including GN
configuration defaults.
