Makefile: Add missing dependency of '.depend' on 'oclobj.h'
...
Without the change parallel build occasionally fails as:
$ make --shuffle
...
gcc ... -c common/opencl.c -o common/opencl-8.o ...
common/opencl.c:116:10: fatal error: common/oclobj.h: No such file or directory
116 | #include "common/oclobj.h"
| ^~~~~~~~~~~~~~~~~
Best reproducible with `make --shuffle` mode:
https://savannah.gnu.org/bugs/index.php?62100
This happens because `common/oclobj.h` is an autogenerated file.
Normally `.depend` would contain this autogenerated dependency.
But nothing forces `common/oclobj.h` to be generated.
The change moves dependency of $(GENERATED) from final binaries
to `.depend` itself:

Unify 8-bit and 10-bit CLI and libraries
...
Add 'i_bitdepth' to x264_param_t with the corresponding '--output-depth' CLI
option to set the bit depth at runtime.
Drop the 'x264_bit_depth' global variable. Rather than hardcoding it to an
incorrect value, it's preferable to induce a linking failure. If applications
relies on this symbol this will make it more obvious where the problem is.
Add Makefile rules that compiles modules with different bit depths. Assembly
on x86 is prefixed with the 'private_prefix' define, while all other archs
modify their function prefix internally.
Templatize the main C library, x86/x86_64 assembly, ARM assembly, AARCH64
assembly, PowerPC assembly, and MIPS assembly.
The depth and cache CLI filters heavily depend on bit depth size, so they
need to be duplicated for each value. This means having to rename these
filters, and adjust the callers to use the right version.
Unfortunately the threaded input CLI module inherits a common.h dependency
(input/frame -> common/threadpool -> common/frame -> common/common) which
is extremely complicated to address in a sensible way. Instead duplicate
the module and select the appropriate one at run time.
Each bitdepth needs different checkasm compilation rules, so split the main
checkasm target into two executables.

Cycle counts are not as stable as one would like. The dynamic code
optimisation seems to produce different results for small chnages in a
binary. Repeated runs with the same binary produce stable results
though (ignoring the first run).
