build: use allowed over enabled or not-disabled

Meson feature options are typically in a tri-state of enabled, disabled,
or auto. The enabled and disabled functions on an option (from
`get_option`) no longer return true for auto features. Instead, the
expectation is to use `allowed()` which is true for both enabled and
auto.

Switch all uses of `enabled` to `allowed`.
Switch all uses of `not disabled` to `allowed`.

For example,
If it is valid config, it will return 8x8 for PE1,3,4,6.
