Message:

ValidationKit/bootsectors: Implement SIMD FP testcases for cvtpi2ps, and fix it in IEM; bugref:10658; jiraref:VBP-1206

IEM:

• fix IEM cvtpi2ps [mem] trashing the target register
• fix IEM cvtpi2ps [mem] sometimes leaving x87/MMX FTW in the wrong state

Valkit:

• fix Bs3ExtCtxSetReg() ability to load MMX registers
• add BS3_REGISTER_IS_MMX macro
• fix test worker's interaction with x87/MMX FTW
• add 'RAND_x6' FP32 value bars for use in tests of these instructions
• add wacky set of macros for injecting integers into FP data arrays
• implement cvtpi2ps tests
