Stop excluding device code from coverage - #1099

GPUCompiler now records line coverage of device code when compiling it (JuliaGPU/GPUCompiler.jl#844, in every 2.x release), so kernels no longer show up as uncovered. Drop the COV_EXCL markers around device code and the src/device codecov ignore, so reports show which device code the tests actually compile. Markers around host code that tests can't reach, like the error description tables, stay.

COV_EXCLmarkers around device code and thesrc/devicecodecov ignore, so reports show which device code the tests actually compile. Markers around host code that tests can't reach, like the error description tables, stay.I checked this with Metal.jl on Julia 1.10 and 1.12 under
--code-coverage: kernel bodies (reduce_warp,broadcast_linear, the scan kernels, ...) show up as covered, and device code that isn't compiled, like the non-shufflereduce_groupfallback, stays uncovered.
