feat(blobs): re-add brillig gates check to protocol circuits

[MirandaWood]

After a new brillig unconstrained gates check was added to noir (possibly noir-lang/noir#6658), this slowed down the compile time of blob code from ~6mins to ~3hrs. To make it mergeable, I temporarily added --skip-brillig-constraints-check to any build commands.
We definitely want to check and catch underconstrained code in the future. Once this can be run in a reasonable time, removed the above flag from:

• noir-projects/Earthfile (f420a79)
• noir-projects/noir-protocol-circuits/bootstrap.sh (e6fc5b5)
