[Formatter] Do not force indentation style unless certain line length were met

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been requested.

Summary

Formatter always format code as the specified indent style no matter how long the statement is:

# before
$foo = if ($true) {1} else {0}

# after 
$foo = if ($true) {
    1
} else {
    0
}

# expected
$foo = if ($true) { 1 } else { 0 }

The code became too sparse by being enforced to the indentation style.

Proposed Design

No response

issue の PowerShell 例を使って formatter の動作を再現し、次に formatter の実装と既存のテストを見つけます。行長の条件がインデントの適用にどのような影響を与えるべきかを判断します。完了の条件は、formatter の既存の動作を壊すことなく、短い文が「expected」の下に示されたコンパクトな形式を維持することです。
