riscv: ptrace: expand "LP" references to "branch landing pads" in uapi headers

Browse Source 
Per Linus' comments about the unreadability of abbreviations such as
"LP", rename the RISC-V ptrace landing pad CFI macro names to be more
explicit.  This primarily involves expanding "LP" in the names to some
variant of "branch landing pad."
