Fix undocumented_unsafe_block recognize safety comments inside blocks and on same line in macros

[borngraced]

fixes false positives for undocumented_unsafe_blocks #16210

Same line comments in macros (e.g., let _x =// SAFETY: ...) and inner safety comments (e.g., unsafe { // SAFETY: ... }) were not recognized because

rust-clippy/clippy_lints/src/undocumented_unsafe_blocks.rs

Line 794 in 4882141

fn text_has_safety_comment(

only checked for lines starting with // or /*.

note: block_has_inner_safety_comment does not respect accept-comment-above-statement or accept-comment-above-attributes. These configs control comments above statements or attributes; inner comments are inside the block, so no ambiguity exists.
