Fix default argument value type checking (#10460)
# Description
Fix type checking in arguments default values not adhering to subtyping
rules
Currently following examples produce a parse error:
```nu
def test [ --qwe: record<a: int> = {a: 1 b: 1} ] { }
def test [ --qwe: list<any> = [ 1 2 3 ] ] { }
```
despite types matching. Type equality check is replaced with subtyping
check and everything parses fine:
# User-Facing Changes
Default values of flag arguments type checking behavior is in line with
`let` statements
