Add qc_blobs repository

This patch adds a separate blobs repository for Qualcomm blobs,
analogous to the existing AMD blobs. Qualcomm's binary licenses allow
files to be redistributed and used by anyone, but they explicitly
require the user to agree to the license terms when just *downloading*
the binary (even if they're not using them to build any firmware). Some
community members do not like to have to agree to licenses for files
they're not actually using, so we are keeping these files separate from
the main blobs repository and adding an extra Kconfig to make sure the
user is aware of and must explicitly agree to this before downloading
these files.
