Description (*)

This PR adds improvement for ability to deploy the only specific theme(s) for multiple locales, so it should improve build phase of deployment for the those who use single theme with different locales.

Basically what I did - i just removed packages from all themes from which inherited requested theme, so in case of Luma - we have only 1 parent theme, but for people who has bigger inheritance - different will be bigger.

How I tested:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f -t Magento/luma -- en_AU en_CA en_IE en_NZ en_GB en_US

Before:
~130 seconds ❌

After:
~65 seconds ✔

Steps to reproduce (*)

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f -t Magento/luma --no-parent -- en_AU en_CA en_IE en_NZ en_GB en_US

Actual result (*)

Content deploy with --no-parent parameter was not available

Performing php bin/magento setup:static-content:deploy -f -t Magento/luma -- en_AU en_CA en_IE en_NZ en_GB en_US finished in 269 seconds

Expected result (*)

php bin/magento setup:static-content:deploy -f -t Magento/luma --no-parent -- en_AU en_CA en_IE en_NZ en_GB en_US became available and finished faster
