This change is in preparation for managing the SiVal silicon configuration using a separate OTP scaffolding. The `//sw/ip/otp_ctrl/data/earlgrey_skus/emulation` targets will contain OTP images used for simulation as well as FPGA emulation. FPGA emulation images will include both pre-silicon and post-silicon use cases. Targets under `//sw/ip/otp_ctrl/data/earlgrey_skus/sival` will be used strictly for configuring silicon for Silicon Validation flows. We refer to this as the SiVal SKU. The SiVal SKU will contain secure boot public keys backed by code-signing infrastructure as opposed to the the `emulation` configuration which will continue to use the test (i.e. fake) keys stored in the repository.

The provisioning firmware contains hardcoded settings for the HWCFG1 partition, and uses data generated at manufacturing time to calculate the DEVICE_ID. As a result, most of the otp image targets and hardware partition settings in the sival SKU, are not derived from the OTP build targets. This change removes unused tardgets to simplify the build / provisioning maintenance. pre-silicon and post-silicon simulation and emulation environments should use the emulation SKU instead.

The use of `CREATOR_SW_CFG_MANUF_STATE` as the SKU identifier is getting deprecated in favor of using the DeviceID. The DeviceID definition contains enough information to constraint code signatures to a particular SKU. The `CREATOR_SW_CFG_MANUF_STATE` will be used to capture the manufacturing state of the device. At the end of manufacturing, there will be a value configured to flag end of manufacturing. Signed-off-by: Miguel Osorio <miguelosorio@google.com>

Backport #25149, #25168 . I don't know if this should be backported or not. Also the history is quite confusing because some changes were partially cherry-picked to master but in a different from the one in earlgrey_1.0.0, see #25168 I had to fix quite a few bazel labels but nothing major.
