Migrate some tests from `tests/ui/issues` to appropriate directories

The following changes have been made in the pull request:

- `tests/ui/issues/issue-25746-bool-transmute.rs` ➝ `tests/ui/transmute/transmute-bool-u8.rs`
- `tests/ui/issues/issue-32377.{rs,stderr}` ➝ `tests/ui/intrinsics/transmute-phantomdata-generic-unequal-size.{rs,stderr}`

The issue links have also been added at the top of each `.rs` file.
