feat(vim.validate): improve fast form and deprecate spec form

Browse Source 
Problem:

`vim.validate()` takes two forms when it only needs one.

Solution:

- Teach the fast form all the features of the spec form.
- Deprecate the spec form.
- General optimizations for both forms.
- Add a `message` argument which can be used alongside or in place
  of the `optional` argument.

Validate function arguments. Validate function arguments.

Form 2 validates a parameter specification (types and values). Specs are `table<string,[value:any, validator: vim.validate.Validator, optional_or_msg? : boolean|string]>)`

Note: ~
• `validator` set to a value returned by |lua-type()| provides the best
performance.
Parameters: ~ Parameters: ~
• {opt} (`table`) Names of parameters to validate. Each key is a • {name} (`string`) Argument name
parameter name; each value is a tuple in one of these forms: • {value} (`string`) Argument value
1. (arg_value, type_name, optional) • {validator} (`vim.validate.Validator`)
• arg_value: argument value • (`string|string[]`): Any value that can be returned
• type_name: string|table type name, one of: ("table", "t", from |lua-type()| in addition to `'callable'`:
"string", "s", "number", "n", "boolean", "b", "function", `'boolean'`, `'callable'`, `'function'`, `'nil'`,
"f", "nil", "thread", "userdata") or list of them. `'number'`, `'string'`, `'table'`, `'thread'`,
• optional: (optional) boolean, if true, `nil` is valid `'userdata'`.
2. (arg_value, fn, msg) • (`fun(val:any): boolean, string?`) A function that
• arg_value: argument value returns a boolean and an optional string message.
• fn: any function accepting one argument, returns true if • {optional} (`boolean?`) Argument is optional (may be omitted)
and only if the argument is valid. Can optionally return • {message} (`string?`) message when validation fails
an additional informative error message as the second
returned value.
• msg: (optional) error string if validation fails
