allow lists to have type annotations (#8529) 
this pr refines #8270 and closes #8109

# description
examples:

the original syntax is okay
```nu
def okay [nums: list] {}         # the type of list will be list<any>
```

empty annotations are allowed in any variation
the last two may be caught by a future formatter, 
but do not affect `nu` code currently
```nu
def okay [nums: list<>] {}       # okay

def okay [nums: list<     >] {}  # weird but also okay

def okay [nums: list<
>] {}                            # also weird but okay
```

types are allowed (See [notes](#notes) below)
```nu
def okay [nums: list<int>] {}    # `test [a b c]` will throw an error 

def okay [nums: list< int > {}   # any amount of space within the angle brackets is okay

def err [nums: list <int>] {}    # this is not okay, `nums` and `<int>` will be parsed as
                                 # two separate params, 
```

nested annotations are allowed in many variations
```nu
def okay [items: list<list<int>>] {}

def okay [items: list<list>] {}
```

any unterminated annotation is caught
```nu
Error: nu::parser::unexpected_eof

  × Unexpected end of code.

   ·                       ╰── expected closing >

```

unknown types are flagged
```nu

  × Unknown type.

```

# notes
the error message for mismatched types in not as intuitive
```nu
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[source:1:1]
 1 │ def err [nums: list<int>] {}; err [a b c]
   ·                                    ┬
   ·                                    ╰── expected int
   ╰────
```
it should be something like this
```nu
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[source:1:1]
 1 │ def err [nums: list<int>] {}; err [a b c]
