Fix for Visual Studio compiler warnings and errors when JVET_R0351_HIGH_BIT_DEPTH_ENABLED is enabled

Fix the prefix problem of some variables names; change the macro from ACT_LMCS_FIX to JVET_S0234_ACT_CRS_FIX.

JVET-S0186: VPS cleanup - move 2 syntax elements, sps_chroma_format_idc and sps_log2_ctu_size_minus5, to take the place of sps_reserved_zero_4bits.

VUI modifications including VUI length, moving two flags from GCI to
VUI, reordering VUI variables to follow syntax elements

Constraint that no subpicture can be outside the conformance cropping
window + rewrite the conformance cropping window when extracting a
subpicture

JVET-S0248 Aspect7: When bp_alt_cpb_params_present_flag is equal to 1, the value of bp_du_hrd_params_present_flag shall be equal to 0

JVET-S0048 Aspect2: change the constraint on the value ranges of scaling window offsets to be more flexible

When pic_width_in_luma_samples is equal to pic_width_max_in_luma_samples and pic_height_in_luma_samples is equal to pic_height_max_in_luma_samples, the value of pps_conformance_window_flag shall be equal to 0

JVET-S0160 aspect 1 and aspect 9: inference of pps_loop_filter_across_tiles_enabled_flag and constraint on ph_poc_msb_cycle_present_flag

The variable invAngle in the VVC specification is signed, whereas
the variable in the software is unsigned.

Silence warnings for potentially invalid array indexes by adding explicit checks.

JVET-S0049 aspect 4: Constrain the value of pps_alf_info_in_ph_flag to be equal to 0 when the PH is in the SH
