wifi: Add support for new SAR tables revisions

Existing SAR infrastructure supports only revision 0 of the SAR tables.
This patch modifies it to extend support for intel wifi 6 and wifi 6e
configurations as per the connectivity document:
559910_Intel_Connectivity_Platforms_BIOS_Guidelines_Rev6_4.pdf

The SAR table and WGDS configuration block sizes were static in the
previous SAR binary format. In the new binary format every
configuration block starts with a revision and the following block size
is calculated based on it, which also supports enabling/disabling a
configuration block by setting the revision to invalid.

BUG=b:193665559
TEST=Checked the SSDT entries for WRDS, EWRD and WGDS with different
binaries generated by setting different versions in the config.star
