Add a custom value "os.arch" of System.getProperty("os.arch")

Something like:

        buildScan.value("os.arch", providers.systemProperty("os.arch").get())

This will help compare build times from Intel machines, compared to ARM based machines.
Also, will help see if certain failures are more common on one or the other.

It's not too bad to do the full cpu part. Can be nice to have when you want to try to advocate for hardware upgrades with specific arguments. Gatta isolate all those variables.

    fun GradleEnterpriseExtension.cpuTag() {
        val os = System.getProperty("os.name")
        buildScan.background {
            val tagValue = when {
                os.contains("Mac", ignoreCase = true) ->
                    execAndGetStdout("sysctl", "-a")?.let {
                        findMacCpuPart(it.split("\n"))
                    }

                os.contains("Linux", ignoreCase = true) ->
                    findLinuxCpuPart(File("/proc/cpuinfo").readLines())

                os.contains("Windows", ignoreCase = true) ->
                    execAndGetStdout("wmic", "cpu", "get", "name")?.let {
                        findWindowsCpuPart(it.split("\n"))
                    }

                else -> null
            }
            value("Cpu", tagValue?.takeIf { it.isNotBlank() } ?: "Unknown CPU")
        }
    }

    fun findMacCpuPart(sysctl: List<String>): String? =
        sysctl.find { it.startsWith("machdep.cpu.brand_string") }
            ?.removePrefix("machdep.cpu.brand_string: ")

    fun findLinuxCpuPart(cpuinfo: List<String>): String? =
        cpuinfo.find { it.contains("model name") }?.split(":")?.last()?.trim()

    fun findWindowsCpuPart(wmic: List<String>): String =
        wmic.last { it.isNotBlank() }

Not the most elegant looking thing, but it's worked pretty well for me.
