[FEA] Support null characters in regular expressions in RLIKE

[andygrove]

Is your feature request related to a problem? Please describe.

Given this input dataset:

• ab
• a\u0000b

The behavior or RLIKE differs between CPU and GPU when the pattern contains a null character:

Pattern	Spark on CPU	Spark on GPU
a\\0b	Illegal octal escape sequence near index 3	Correct result
a\0b	Correct result	Incorrect result
a\u0000b	Correct result	Incorrect result
a\\x00b	Correct result	Correct result

Describe the solution you'd like
Ideally, we should have the same behavior as Spark but if this is not possible then we could consider falling back to CPU and maybe having a separate config to enable/disable supporting null characters in regex.

Describe alternatives you've considered
None
