Merge #1077
1077: Improve parsing of type bounds r=matklad a=vipentti
This adds new TYPE_BOUND_LIST and TYPE_BOUND syntax kinds. These are now used when parsing type bounds. In addition parsing paths inside a bound now does not recursively parse paths, rather they are treated as separate bounds, separated by +.
Basically now the generic params `struct S<T: 'a + ?Sized + (Copy)>;` in will be parsed as
```
TYPE_PARAM_LIST@[8; 33)
L_ANGLE@[8; 9)
TYPE_PARAM@[9; 32)
NAME@[9; 10)
IDENT@[9; 10) "T"

NAME_REF@[27; 31)
IDENT@[27; 31) "Copy"
R_PAREN@[31; 32)
R_ANGLE@[32; 33)
```
Previously it was parsed, with the paths nested:
```
TYPE_PARAM_LIST@[8; 33)
L_ANGLE@[8; 9)
TYPE_PARAM@[9; 32)
NAME@[9; 10)
IDENT@[9; 10) "T"

WHITESPACE@[16; 17)
QUESTION@[17; 18)
PATH_TYPE@[18; 32)
PATH@[18; 23)
PATH_SEGMENT@[18; 23)
NAME_REF@[18; 23)
IDENT@[18; 23) "Sized"
WHITESPACE@[23; 24)
PLUS@[24; 25)
WHITESPACE@[25; 26)
L_PAREN@[26; 27)
PATH_TYPE@[27; 31)
PATH@[27; 31)
PATH_SEGMENT@[27; 31)
NAME_REF@[27; 31)
IDENT@[27; 31) "Copy"
R_PAREN@[31; 32)
R_ANGLE@[32; 33)
```
Looking for feedback.
