elf: Add GNU_PROPERTY_UINT32_AND_XXX/GNU_PROPERTY_UINT32_OR_XXX

Implement GNU_PROPERTY_UINT32_AND_XXX/GNU_PROPERTY_UINT32_OR_XXX:

https://sourceware.org/pipermail/gnu-gabi/2021q1/000467.html

1. GNU_PROPERTY_UINT32_AND_LO..GNU_PROPERTY_UINT32_AND_HI

 #define GNU_PROPERTY_UINT32_AND_LO 0xb0000000
 #define GNU_PROPERTY_UINT32_AND_HI 0xb0007fff

A bit in the output pr_data field is set only if it is set in all
relocatable input pr_data fields.  If all bits in the the output
pr_data field are zero, this property should be removed from output.

If the bit is 1, all input relocatables have the feature.  If the
bit is 0 or the property is missing, the info is unknown.

2. GNU_PROPERTY_UINT32_OR_LO..GNU_PROPERTY_UINT32_OR_HI

 #define GNU_PROPERTY_UINT32_OR_LO 0xb0008000
 #define GNU_PROPERTY_UINT32_OR_HI 0xb000ffff

A bit in the output pr_data field is set if it is set in any
relocatable input pr_data fields. If all bits in the the output
pr_data field are zero, this property should be removed from output.

If the bit is 1, some input relocatables have the feature.  If the
bit is 0 or the property is missing, the info is unknown.
