Fix incorrect handling of boolean flags for builtin commands (#11492)

# Description
Possible fix of #11456
This PR fixes a bug where builtin commands did not respect the logic of
dynamically passed boolean flags. The reason is
[has_flag](6f59abaf43/crates/nu-protocol/src/ast/call.rs (L204C5-L212C6))
method did not evaluate and take into consideration expression used with
flag.

To address this issue a solution is proposed:
1. `has_flag` method is moved to `CallExt` and new logic to evaluate
expression and check if it is a boolean value is added
2. `has_flag_const` method is added to `CallExt` which is a constant
version of `has_flag`
3. `has_named` method is added to `Call` which is basically the old
logic of `has_flag`
4. All usages of `has_flag` in code are updated, mostly to pass
`engine_state` and `stack` to new `has_flag`. In `run_const` commands it
is replaced with `has_flag_const`. And in a few select places: parser,
`to nuon` and `into string` old logic via `has_named` is used.

# User-Facing Changes
Explicit values of boolean flags are now respected in builtin commands.
