Rollup merge of #143104 - davidtwco:issue-142652-dyn-pointeesized-deny, r=compiler-errors

hir_analysis: prohibit `dyn PointeeSized`

Fixes #142652
Supersedes #142663

`dyn PointeeSized` is nonsensical as a `dyn PointeeSized` needs to be `MetaSized`, so lets reject it to avoid hitting code paths that expect a builtin impl for `PointeeSized`

r? `@compiler-errors`
