Disable Windows coverage tracking for now (#8190)

# Description

Avoids running out of disk through additional files after cratification
on Windows.

Revert as soon as we reduced the binary or test footprint.

Will mess with the coverage values without change in test suite as we
only track the linux conditional compilation

Should resolve the CI failure for #8181 

# User-Facing Changes

None

# Tests + Formatting

Altered coverage value thresholds might be the result
