[libc++][ranges] Adjust inheritance detection for `enable_view` (#132582)

Per [range.view]/6, a `view_interface` isn't a base class of itself, so
`enable_view` should report `false`. Also, current implementation
strategy handles `const` but not `volatile`, IIUC cv-qualifiers should
be consistent handled.

In `enable_view.compile.pass.cpp`, coverage for (`const`) `volatile`
types are added.

Drive-by: Remove one unnessary `test_macro.h` inclusion in a test.

Fixes #132577.
