  [MCA] Optimize memory consumption in resource pressure view (NFC) (#124904)

ResourceUsage is a very sparse table. On large input asm sequences it
consumes a lot of memory utilizing only a few percents of it (~4% on my
benchmark). Reorganization of ResourceUsage to keep only used fields
allows saving up to 18% of total memory use by mca or ~850% of input
file size (~1.1GB in absolute values in my case).
