[FEAT][BREAKING][2/2][member-delimiter-style] Separate single/multiline config

[bradzacher]

PRing against #203's branch for now so it's easier to see the changes in this PR.

Breaking change:

Changed config to split single and multiline config into two separate objects for better customisability
Before:

type Delimiter = 'none' | 'semi' | 'comma';
interface BaseConfig {
    delimiter ?: Delimiter
    requireLast ?: boolean
    singleLine ?: Delimiter
}
type Config = BaseConfig & {
    overrides ?: {
        interface ?: BaseConfig
        typeLiteral ?: BaseConfig
    }
}

After:

type Delimiter = 'none' | 'semi' | 'comma';
interface BaseConfig {
    multiline ?: {
        delimiter ?: 'none' | 'semi' | 'comma'
        requireLast ?: boolean
    }
    singleline ?: {
        delimiter ?: 'semi' | 'comma'
        requireLast ?: boolean
    }
}
type Config = BaseConfig & {
    overrides ?: {
        interface ?: BaseConfig
        typeLiteral ?: BaseConfig
    }
}
