fix(codegen): remove leading whitespace from export statements after comments

[Boshen]

Summary

• Clear the print_next_indent_as_space flag after printing comments in ExportSpecifier to prevent it from leaking to subsequent statements

When a block comment like /* comment */ is printed inside an export specifier, the flag is set expecting print_indent() to consume it. However, ExportSpecifier calls print_soft_space() instead, leaving the flag set. This caused the next export statement to incorrectly print a leading space.

Before:

export { name8, /* comment */ name81 };
 export { variable1 as name9 };  // <-- unwanted leading space

After:

export { name8, /* comment */ name81 };
export { variable1 as name9 };

Test plan

• Existing tests pass
• Snapshot updated to reflect the fix

Closes #17884

Pull request overview

This PR fixes a bug where leading whitespace was incorrectly added to export statements following block comments within export specifiers. The issue occurred because the print_next_indent_as_space flag, set by print_comments(), was not being consumed when print_soft_space() was called instead of print_indent().

Changes:

• Reset the print_next_indent_as_space flag after printing comments in ExportSpecifier to prevent flag leakage
• Update test snapshot to reflect corrected output format
