Add support for '-Dstrip=true' and '--auto-features=disabled' in "arch-meson"

Description:

The current packaging wrapper for Arch Linux does not include support for the -Dstrip=true flag and the --auto-features=disabled option. These are often used to control build behavior and should be incorporated into the wrapper for better customization and control during the packaging process.

Additional info:

• -Dstrip=true: Strips debugging symbols from the final package, reducing its size.
• --auto-features=disabled: Disables automatic enabling of features based on system configuration, giving the user more explicit control over the build features.

Package version(s):

• 1.9.1

---

Steps to reproduce:

1. Modify the wrapper script to add -Dstrip=true and --auto-features=disabled.
2. Run the script with a typical package configuration to confirm the changes.

Example modified wrapper:

#!/bin/bash -ex
# Highly opinionated wrapper for Arch Linux packaging

exec meson setup \
  --prefix        /usr \
  --libexecdir    lib \
  --sbindir       bin \
  --buildtype     plain \
  --auto-features disabled \   # Change here from enabled to disabled
  --wrap-mode     nodownload \
  -D              b_pie=true \
  -D              python.bytecompile=1 \
  -D              strip=true \  # Change here to add strip
  "$@"

This update will provide more efficient builds with stripping enabled by default and more predictable feature management, particularly for users who require fine-grained control over their build features.
