  -----------
  [Driver] Add support for crtbegin.o, crtend.o and libgloss lib to BareMetal toolchain object (#121830)

This patch conditionalise the addition of crt{begin,end}.o object files
along
with addition of -lgloss lib based on whether libc selected is newlib or
llvm
libc. Since there is no way a user can specify which libc it wants to
link
against, currently passing valid GCCInstallation to driver will select
newlib
otherwise it will default to llvm libc.

Moreover, this patch makes gnuld the default linker for baremetal
toolchain
object. User need to pass `-fuse-ld=lld` explicitly to driver to select
lld

This is the 2nd patch in the series of patches of merging RISCVToolchain
into
BareMetal toolchain object.
