[Linux/x86] Use ebp from current context during unwinding (#26789)

pCurrentContextPointers in REGDISPLAY can contain NULLs so we need to use
ebp value from pCurrentContext. This patch contains following changes:

- GetRegdisplayFP returns ebp from pCurrentContext
- GetRegdisplayFP is used instead of *GetEbpLocation()
- Set##reg##Location also updates register value in pCurrentContext
