build.config.gki sources a GKI_BUILD_CONFIG_FRAGMENT before all of
the variables that are considered as part of a GKI kernel build are
declared. This reduces the effectiveness of a
GKI_BUILD_CONFIG_FRAGMENT, as it is only able to modify a subset of
the build variables.
Thus, move the logic to source GKI_BUILD_CONFIG_FRAGMENT to the end
of the GKI build config files to provide more flexibility for a
GKI_BUILD_CONFIG_FRAGMENT.

[isaacmanjarres: Modified build.config.gki.aarch64.fips140, which
did not exist on android13-5.15.]

(cherry picked from commit 69fefbb3db711e543ff0676526b7d285a4d10a14)
As a result of this change:
- fips140 is no longer part of the GKI build but a
separate module, so it is not signed
(CONFIG_MODULE_SIG_ALL is not set)
- GKI images (e.g. system_dlkm image, boot images)
etc. are no longer part of the build -- because
they are unnecessary.
- The build config no longer inherits from build.config.gki.aarch64
directly to avoid building unnecessary system_dklm, boot images,
GKI artifacts, etc.

To meet FIPS 140 requirements, add support for building a kernel module
"fips140.ko" that contains various cryptographic algorithms built from
existing kernel source files. At load time, the module checks its own
integrity and self-tests its algorithms, then registers the algorithms
with the crypto API to supersede the original algorithms provided by the
kernel itself.
[ebiggers: this commit originated from "ANDROID: crypto: fips140 -
perform load time integrity check", but I've folded many later commits
into it to make forward porting easier. See below]
