Cleanup: use uint8_t for various flags in curves

Previously, it was kind of a mess. In different places it was using `char`, `short` and `int`.

The changed properties are flags that are operated upon using bit operations. Therefore, the integer type should be unsigned. Since we only use 2 bits of these flags, `uint8_t` is large enough.

Especially note the change I had to make in `RNA_define.h` to make this work.
