target/arm: Rename CP_ACCESS_TRAP_UNCATEGORIZED to CP_ACCESS_UNDEFINED

CP_ACCESS_TRAP_UNCATEGORIZED is technically an accurate description
of what this return value from a cpreg accessfn does, but it's liable
to confusion because it doesn't match how the Arm ARM pseudocode
indicates this case. What it does is an EXCP_UDEF with a zero
("uncategorized") syndrome value, which is what an UNDEFINED instruction
does. The pseudocode uses "UNDEFINED" to show this; rename our
constant to CP_ACCESS_UNDEFINED to make the parallel clearer.

Commit created with
sed -i -e 's/CP_ACCESS_TRAP_UNCATEGORIZED/CP_ACCESS_UNDEFINED/' $(git grep -l CP_ACCESS_TRAP_UNCATEGORIZED)

plus manual editing of the comment.
