Build::Archsrcinfo: use .SRCINFO as a choice of build recipe for Arch

[YukariChiba]

Introduce the capability to use .SRCINFO files as alternative build recipe for Arch Linux packages.

Using static .SRCINFO files is a faster and more reliable method for extracting package metadata (like dependencies, version, and source URLs).

Usage:

1. As the current service does not support hidden files beginning with a dot, .SRCINFO files must be renamed to SRCINFO:

<services>
  <service name="tar_scm">
    <param name="url">%URL%</param>
    <param name="scm">git</param>
    <param name="extract">*</param>
    <param name="extract-rename">.SRCINFO:SRCINFO</param>
  </service>
</services>

2. Type: archsrcinfo needs to be added into project config.
