Daniel Henrique Barboza 583edc4efb riscv, gdbstub.c: fix reg_width in ricsv_gen_dynamic_vector_feature() ...

Commit 33a24910ae changed 'reg_width' to use 'vlenb', i.e. vector length
in bytes, when in this context we want 'reg_width' as the length in
bits.

Fix 'reg_width' back to the value in bits like 7cb59921c0
("target/riscv/gdbstub.c: use 'vlenb' instead of shifting 'vlen'") set
beforehand.

While we're at it, rename 'reg_width' to 'bitsize' to provide a bit more
clarity about what the variable represents. 'bitsize' is also used in
riscv_gen_dynamic_csr_feature() with the same purpose, i.e. as an input to
gdb_feature_builder_append_reg().
