feat(lx2162aqds): add trusted boot builds

PLAT=lx2162aqds build with custom tbbr from nxp tbbr cot file and
this build can be without mbedtls dir specified.

This is a special configuration used so add this to l1 group tests.

Align all mbedtls downloads to archive paths and avoid
using ref/tags in url.
