soc/intel/cmn/block/cse: Add support for explicit CSE_RW_VERSION

Browse Source 
This change adds support for specifying the CSE_RW_VERSION directly in
Kconfig.

* If `CONFIG_SOC_INTEL_CSE_RW_VERSION` is defined, its value will be
  used directly as the CSE_RW version.
* Otherwise, the version will be extracted from the CSE_RW binary file
  as before.

Platform prior to Intel Meteor Lake still requires to override the CSE
RW version using CONFIG_SOC_INTEL_CSE_RW_VERSION config rather reading
the CSE RW version from CSE RW partition.

BUG=b:327842062
TEST=CSE RW update successful on Karis with this patch using below
recipe:

1. Overriding the CONFIG_SOC_INTEL_CSE_RW_VERSION="18.0.5.2269"
2. Without overriding the CONFIG_SOC_INTEL_CSE_RW_VERSION=""

Platform prior to Intel Meteor Lake would be using #1 and platform
starting with Meteor Lake expected to use #2 recipe.
