Handle Blocks with the Same Name as Functions or Keywords as Word Blocks

[xterao]

Summary
This PR fixes unintended formatting when column names are identical to SQL functions or reserved keywords. Previously, such identifiers were not treated as normal word blocks, leading to incorrect formatting results.

Relation
#423

Details

• Columns or identifiers that share names with functions or keywords are now treated as word blocks.
• Escaped identifiers (e.g., "age") are also handled consistently to prevent unwanted formatting changes.

Adjustments for Escaped Identifiers:

• Disable keyword capitalization for escaped words.
• Do not create keyword groups for them.
• Apply the same spacing rules as for word blocks, including consistent spacing around escape characters.
• When a column definition uses escape characters, align the indentation to the right the same way as with normal column names.
• When enclosed in escape characters, calculate spacing based on the total character length, including the escape characters.

Impact

• Prevents unexpected line breaks or keyword formatting when column names overlap with reserved words or functions.
• Ensures escaped identifiers maintain proper indentation and spacing.

• Handle escaped identifiers (e.g., "age", [abs]) consistently as word blocks without keyword capitalization
• Improve spacing and indentation logic for escaped identifiers and conditional expressions
• Add test coverage for function names used as column identifiers
