ARM-CI: Convert Linux ARM emulator CI check to cross build (fixes PR #5680)

• Previously used emulated build took a lot of time leading to timeout errors
• Changing this CI check to build using cross build
• Resolves CI issues caused by previous identical PR ARM-CI: Convert Linux ARM emulator CI check to cross build #5680

@jashook @mmitche @wtgodbe I have made a new PR (identical to PR #5680 ) with the environment variable error fixed.

Summary of changes from PR #5680 are

• armarmemul_path and armrootfs_mountpath are now declared as groovy variables (instead of bash shell variables)
• The above groovy variables are used in the build commands using groovy string interpolation (${})
• The $LINUX_ARM_INCPATH and $LINUX_ARM_CXXFLAGS environment variables are used in the build commands with the $ escaped (need comments on correctness of this change). I am assuming that the previous error was due to groovy parsing the $ symbol according to its string interpolation rules, and that the commands in the exact string form will be executed on the bash shell.

Could you please review this PR and confirm if the above summarized changes fixes the errors caused by PR #5680 ?

@dotnet-bot test CI Please

@jashook The previous version of this PR was breaking the CI test due to the assert condition to test if the configuration that is being built was one of either Debug or Release. I have changed this check to an if condition (breaking if the configuration is neither of the two).

@dotnet-bot test CI please

Thanks for doing this! Everything looks good to me (I believe escaping the $ before $LINUX_ARM_INCPATH was the right thing to do, but you might want to get a second opinion on this one. The CI test passing is a pretty good indicator that it was correct, though).

@jashook Can we merge this?
