[SHELL32] Load shell icon size from registry (#7683)
Improve usability. Re-trial of #7679 with different approach.
JIRA issue: CORE-12905
- Add ShellSmallIconSize, ShellLargeIconSize, and
ShellIconBPP global variables in iconcache.cpp.
- Add SIC_GetMetricsValue, SIC_GetLargeIconSize,
SIC_GetSmallIconSize, and SIC_GetIconBPP helper
functions in iconcache.cpp.
- Load shell icon size from registry key
"HKEY_CURRENT_USER\\Control Panel\\Desktop\\WindowMetrics".
- Load icon BPP (bits per pixel) from registry.
- Fix SIC_Initialize and SIC_LoadIcon functions for icon size.
- Fix SHGetFileInfoW function for SHGFI_SHELLICONSIZE flag.
