[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

Reproduce the formatter behavior with the PowerShell example in the issue, then locate the formatter implementation and its existing tests. Determine how the line-length condition should affect indentation enforcement; done means short statements retain the compact form shown under “expected” without breaking the formatter’s existing behavior.
