Fix Output.enable_ansi_colors usage to check stdout vs stderr (#24212)

## Summary

Updated all 49 usages of `Output.enable_ansi_colors` to properly check
either `Output.enable_ansi_colors_stdout` or
`Output.enable_ansi_colors_stderr` based on their output destination.

This prevents bugs where ANSI colors are checked against the wrong
stream (e.g., checking stdout colors when writing to stderr).

## Changes

### Added
- `Output.enable_ansi_colors` now a `@compileError` to prevent future
misuse with helpful error message directing to correct variants

### Deleted
- `Output.isEmojiEnabled()` - replaced all usages with
`enable_ansi_colors_stderr` (all were error/progress output)
- `Output.prettyWithPrinterFn()` - removed unused dead code

### Updated by Output Destination

**Stderr (error/diagnostic output):**
- logger.zig: Log messages and errors
- crash_handler.zig: Crash reports and stack traces (10 instances)
- PackageInstaller.zig: Error messages from lifecycle scripts (3
instances)
- JSValue.zig: Test expectation error messages
- JSGlobalObject.zig: Exception throwing
- pack_command.zig: Progress indicators
- VirtualMachine.zig: Exception printing (2 instances)
- Test expect files: Test failure messages and diffs (10 instances)
- diff_format.zig: Test diff output
- ProgressStrings.zig: Package manager progress emojis (6 functions)
- security_scanner.zig: Security scan progress emoji
- output.zig: panic(), resetTerminal()

**Stdout (primary output/interactive UI):**
- hot_reloader.zig: Terminal clearing on reload
- Version.zig: Version diff formatting
- install_with_manager.zig: Package installation tree
- update_interactive_command.zig: Interactive update UI (2 instances)
- init_command.zig: Interactive radio buttons
- create_command.zig: Template creation output (2 instances)
- outdated_command.zig: Outdated packages table
- publish_command.zig: Box drawing characters (6 instances)

**Backward Compatible:**
- BunObject.zig: `Bun.enableANSIColors` property returns `(stdout ||
stderr)` to maintain compatibility
- fmt.zig: Removed unused `.default` field from Options struct

## Test Plan

- ✅ All changes compile successfully with `bun run zig:check`
- ✅ Verified all 49 usages have been updated to appropriate variant
- ✅ Verified no remaining references to deprecated functions/variables
- ✅ Compile error triggers if someone tries to use
`Output.enable_ansi_colors`
