[libclc] Update license headers (#132070)
This commit bulk-updates the libclc license headers to the current
Apache-2.0 WITH LLVM-exception license in situations where they were
previously attributed to AMD - and occasionally under an additional
single individual contributor - under an MIT license.

AMD signed the LLVM relicensing agreement and so agreed for their past
contributions under the new LLVM license.

The LLVM project also has had a long-standing, unwritten, policy of not
adding copyright notices to source code. This policy was recently
written up [1]. This commit therefore also removes these copyright
notices at the same time.

Note that there are outstanding copyright notices attributed to others -
and many files missing copyright headers - which will be dealt with in
future work.
