Rollup merge of #150501 - qb42:patch-1, r=workingjubilee

Fix Typos in Platform Support Tables

3 recently demoted targets had their entries moved to the tier 3 table without adjusting for the extra "host" column, this PR adds an empty column so they display correctly.

2 recently promoted targets had the opposite problem, also fixed.

While doing that I noticed that empty columns were represented inconsistently throughout the file so I normalized them all to be 2 spaces, which seemed to be the majority opinion (139 instances vs 5 for 1 space and 19 for 3 spaces).

Closes: #150499
