Message:

Clean up PAGE_* flags.

Remove "nop flags", they are confusing for readers and any benefit they would
gain in self-documentation they lose in being used inconsistently.

Remove "PAGE_READ", the only place it's used meaningfully is the incomplete
RISC-V implementation, and most call sites assume read is implied.
